Allwinner System-on-Chips usually contain a Real Time Clock (RTC)
for non-volatile system date and time keeping. This commit adds a generic
Allwinner RTC device that supports the RTC devices found in Allwinner SoC
family sun4i (A10), sun7i (A20) and sun6i and newer (A31, H2+, H3, etc).
The following RTC functionality and features are implemented:
* Year-Month-Day read/write
* Hour-Minute-Second read/write
* General Purpose storage
The following boards are extended with the RTC device:
* Cubieboard (hw/arm/cubieboard.c)
* Orange Pi PC (hw/arm/orangepi.c)

The Allwinner System on Chip families sun4i and above contain
an integrated storage controller for Secure Digital (SD) and
Multi Media Card (MMC) interfaces. This commit adds support
for the Allwinner SD/MMC storage controller with the following
emulated features:
* DMA transfers
* Direct FIFO I/O
* Short/Long format command responses
* Auto-Stop command (CMD12)
* Insert & remove card detection
The following boards are extended with the SD host controller:
* Cubieboard (hw/arm/cubieboard.c)
* Orange Pi PC (hw/arm/orangepi.c)

Instantiate EHCI and OHCI controllers on Allwinner A10. OHCI ports are
modeled as companions of the respective EHCI ports.
With this patch applied, USB controllers are discovered and instantiated
when booting the cubieboard machine with a recent Linux kernel.

By calling qdev_pass_gpios() we don't need to hold a copy of the
IRQs from the INTC into the SoC state.
Instead of filling an array of qemu_irq and passing it around, we
can now directly call qdev_get_gpio_in() on the SoC.

In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).
Almost a third of its inclusions are actually superfluous. Delete
them. Downgrade two more to qapi/qapi-types-run-state.h, and move one
from char/serial.h to char/serial.c.
hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and
stubs/semihost.c define variables declared in sysemu/sysemu.h without
including it. The compiler is cool with that, but include it anyway.
This doesn't reduce actual use much, as it's still included into
widely included headers. The next commit will tackle that.

According to hw/ide/internal's file comment, only files in hw/ide/ are
supposed to include it. Drag reality slightly closer to supposition.
Three includes outside hw/ide remain: hw/arm/sbsa-ref.c,
include/hw/ide/pci.h, and include/hw/misc/macio/macio.h. Turns out
board code needs ide-internal.h to wire up IDE stuff. More cleanup is
needed. Left for another day.

Back in 2016, we discussed[1] rules for headers, and these were
generally liked:
1. Have a carefully curated header that's included everywhere first. We
got that already thanks to Peter: osdep.h.
2. Headers should normally include everything they need beyond osdep.h.
If exceptions are needed for some reason, they must be documented in
the header. If all that's needed from a header is typedefs, put
those into qemu/typedefs.h instead of including the header.
3. Cyclic inclusion is forbidden.
This patch gets include/ closer to obeying 2.
It's actually extracted from my "[RFC] Baby steps towards saner
headers" series[2], which demonstrates a possible path towards
checking 2 automatically. It passes the RFC test there.

This is the common header guard idiom:
/*
* File comment
*/
#ifndef GUARD_SYMBOL_H
#define GUARD_SYMBOL_H
... actual contents ...
#endif
A few of our headers have some #include before the guard.
target/tilegx/spr_def_64.h has #ifndef __DOXYGEN__ outside the guard.
A few more have the #define elsewhere.
Change them to match the common idiom. For spr_def_64.h, that means
dropping #ifndef __DOXYGEN__. While there, rename guard symbols to
make scripts/clean-header-guards.pl happy.

and adjust its header comment.

From the "A10 User Manual V1.20" p.29: "3.2. Memory Mapping" and:
7. System Control
7.1. Overview
A10 embeds a high-speed SRAM which has been split into five segments.
See detailed memory mapping in following table:
Area Address Size (Bytes)
A1 0x00000000-0x00003FFF 16K
A2 0x00004000-0x00007FFF 16K
A3 0x00008000-0x0000B3FF 13K
A4 0x0000B400-0x0000BFFF 3K
Since for emulation purpose we don't need the segmentations, we simply define
the 'A' area as a single 48KB SRAM.
We don't implement the following others areas:
- 'B': 'Secure RAM' (64K),
- 'C': Debug/ISP SRAM
- 'D': USB SRAM
