The existing ADB state machine is designed to work with Linux which has a different
interpretation of the state machine detailed in "Guide to the Macintosh Family
Hardware". In particular the current Linux implementation includes an extra change
to IDLE state when switching the VIA between send and receive modes which does not
occur in MacOS, and omitting this transition causes the current mac_via ADB state
machine to fail.
Rework the ADB state machine accordingly so that it can enumerate and autopoll the
ADB under both Linux and MacOS, including the addition of the new adb_autopoll_block()
and adb_autopoll_unblock() functions.

Commit 84051eb400 "adb: add property to disable direct reg 3 writes" introduced
a workaround for spurious writes to ADB register 3 when MacOS 9 enables
autopoll on the mouse device. Further analysis shows that the problem is that
only a partial request is sent, and since the len parameter is ignored then
stale data from the previous request is used causing the incorrect address
assignment.
Remove the disable-reg3-direct-writes workaround and instead check the length
parameter when the write is attempted, discarding the invalid request.

The floppy controller devices desugar their drive properties into
floppy devices (since commit a92bd191a4 "fdc: Move qdev properties to
FloppyDrive", v2.8.0). This involves some bad magic in
fdctrl_connect_drives(), and exists for backward compatibility.
The functions for boards to create floppy controller devices
fdctrl_init_isa(), fdctrl_init_sysbus(), and sun4m_fdctrl_init()
desugar -drive if=floppy to these floppy controller drive properties.
If you use both -drive if=floppy (or its -fda / -fdb sugar) and
-global isa-fdc for the same floppy device, -global silently loses the
conflict, and both backends involved end up with the floppy device
frontend attached, as demonstrated by iotest 172 (see commit before
previous). This is wrong.
Desugar -drive if=floppy straight to floppy devices instead, with
helper fdctrl_init_drives(). The conflict now gets rejected cleanly:
first, fdctrl_connect_drives() creates the floppy for the controller's
property, then fdctrl_init_drives() attempts to create the floppy for
-drive if=floppy, but fails because the unit is already in use.
Output of iotest 172 changes in three ways:
1. The clash gets rejected.
2. In one test case, "info qtree" has the floppy devices swapped, and
"info block" has their QOM paths swapped. This is because the
floppy device for -fda now gets created after the one for -global
isa-fdc.driveB.
3. The error message for -global floppy.drive=floppy0 changes. Before
the patch, we set isa-fdc.driveA to -fda's block backend, then
create the floppy device for it, then move the backend from
isa-fdc.driveA to floppy.drive. Floppy creation fails when
applying -global floppy.drive=floppy0, because floppy0 is still
attached to isa-fdc. After the patch, we create the floppy for
-fda, then set its drive property to floppy0. Now floppy creation
succeeds, but setting the drive property fails, because -global
already set it. Yes, this is exasperatingly complicated.

It is enough to simply map the SiFive FU540 DDR memory controller
into the MMIO space using create_unimplemented_device(), to make
the upstream U-Boot v2020.07 DDR memory initialization codes happy.
Note we do not generate device tree fragment for the DDR memory
controller. Since the controller data in device tree consumes a
very large space (see fu540-hifive-unleashed-a00-ddr.dtsi in the
U-Boot source), and it is only needed by U-Boot SPL but not any
operating system, we choose not to generate the fragment here.
This also means when testing with U-Boot SPL, the device tree has
to come from U-Boot SPL itself, but not the one generated by QEMU
on the fly. The memory has to be set to 8GiB to match the real
HiFive Unleashed board when invoking QEMU (-m 8G).
With this commit, QEMU can boot U-Boot SPL built for SiFive FU540
all the way up to loading U-Boot proper from MMC:
$ qemu-system-riscv64 -nographic -M sifive_u,msel=6 -m 8G -bios u-boot-spl.bin
U-Boot SPL 2020.07-rc3-00208-g88bd5b1 (Jun 08 2020 - 20:16:10 +0800)
Trying to boot from MMC1
Unhandled exception: Load access fault
EPC: 0000000008009be6 TVAL: 0000000010050014
The above exception is expected because QSPI is unsupported yet.

SiFive FU540 SoC supports booting from several sources, which are
controlled using the Mode Select (MSEL[3:0]) pins on the chip.
Typically, the boot process runs through several stages before it
begins execution of user-provided programs.
The SoC supports booting from memory-mapped QSPI flash, which is
how start_in_flash property is used for at present. This matches
MSEL = 1 configuration (QSPI0).
Typical booting flows involve the Zeroth Stage Boot Loader (ZSBL).
It's not necessary for QEMU to implement the full ZSBL ROM codes,
because we know ZSBL downloads the next stage program into the L2
LIM at address 0x8000000 and executes from there. We can bypass
the whole ZSBL execution and use "-bios" to load the next stage
program directly if MSEL indicates a ZSBL booting flow.

On SiFive FU540 SoC, the value stored at physical address 0x1000
stores the MSEL pin state that is used to control the next boot
location that ROM codes jump to.
Add a new property msel to sifive_u machine for this.
