This adds support for nvdimm hotplug events through GED
and enables nvdimm for the arm/virt. Now Guests with ACPI
can have both cold and hot plug of nvdimms.
Hot removal functionality is not yet supported.

This patch makes IO base and size configurable to create NPIO AML for
ACPI NFIT. Since a different architecture like AArch64 does not use
port-mapped IO, a configurable IO base is required to create correct
mapping of ACPI IO address and size.

As per ACPI spec 6.3, Table 19-419 Object Conversion Rules, if
the Buffer Field <= to the size of an Integer (in bits), it will
be treated as an integer. Moreover, the integer size depends on
DSDT tables revision number. If revision number is < 2, integer
size is 32 bits, otherwise it is 64 bits. Current NVDIMM common
DSM aml code (NCAL) uses CreateField() for creating DSM output
buffer. This creates an issue in arm/virt platform where DSDT
revision number is 2 and results in DSM buffer with a wrong
size(8 bytes) gets returned when actual length is < 8 bytes.
This causes guest kernel to report,
"nfit ACPI0012:00: found a zero length table '0' parsing nfit"
In order to fix this, aml code is now modified such that it builds
the DSM output buffer in a byte by byte fashion when length is
smaller than Integer size.

With virtio-vga, pci bar are reordered. Bar #2 is used for compatibility
with stdvga. By default, bar #2 is used by virtio modern io bar.
This bar is the last one introduce in the virtio pci bar layout and it's
crushed by the virtio-vga reordering. So virtio-vga and
modern-pio-notify are incompatible because virtio-vga failed to
initialize with this option.
This fix sets the modern io bar to the bar #5 to avoid conflict.

Calling g_mapped_file_unref() on a NULL pointer is not valid, and
glib will assert if you try it.
$ qemu-system-arm -M virt -display none -device loader,file=/tmp/bad.elf
qemu-system-arm: -device loader,file=/tmp/bad.elf: GLib: g_mapped_file_unref: assertion 'file != NULL' failed
(One way to produce an ELF file that fails like this is to copy just
the first 16 bytes of a valid ELF file; this is sufficient to fool
the code in load_elf_ram_sym() into thinking it's an ELF file and
calling load_elf32() or load_elf64().)
The failure-exit path in load_elf can be reached from various points
in execution, and for some of those we haven't yet called
g_mapped_file_new_from_fd(). Add a condition to the unref call so we
only call it if we successfully created the GMappedFile to start with.
This will fix the assertion; for the specific case of the generic
loader it will then fall back from "guess this is an ELF file" to
"maybe it's a uImage or a hex file" and eventually to "just load as
a raw data file".

Michael Walle expressed his desire to orphan the lm32 target [*]:
I guess it is time to pull the plug. Mainly, because I have
no time for this anymore. I've always worked on this on my
spare time and life changed. And secondly, I guess RISC-V is
taking over ;) It has a far better ecosystem. Also, to my
knowledge the only (public) user of LM32 is milkymist and this
project is dead for years now..
So time to say goodbye. It was fun and I've learned a lot -
technically and also how a huge open source project works.
Thank you everyone for that :)
Basically everything still works and there are even TCG test
cases which covers all instructions the processor has.
Many thanks to Michael for his substantial contributions to QEMU,
and for maintaining the LM32 target for various years!

Convert the Neon logic ops in the 3-reg-same grouping to decodetree.
Note that for the logic ops the 'size' field forms part of their
decode and the actual operations are always bitwise.

Convert the Neon 3-reg-same VADD and VSUB insns to decodetree.
Note that we don't need the neon_3r_sizes[op] check here because all
size values are OK for VADD and VSUB; we'll add this when we convert
the first insn that has size restrictions.
For this we need one of the GVecGen*Fn typedefs currently in
translate-a64.h; move them all to translate.h as a block so they
are visible to the 32-bit decoder.

Convert the Neon "load/store single structure to one lane" insns to
decodetree.
As this is the last set of insns in the neon load/store group,
we can remove the whole disas_neon_ls_insn() function.

Convert the VFM[AS]L (scalar) insns in the 2reg-scalar-ext group
to decodetree. These are the last ones in the group so we can remove
all the legacy decode for the group.
Note that in disas_thumb2_insn() the parts of this encoding space
where the decodetree decoder returns false will correctly be directed
to illegal_op by the "(insn & (1 << 28))" check so they won't fall
into disas_coproc_insn() by mistake.

Convert the VFM[AS]L (vector) insns to decodetree. This is the last
