Unlike gcc, clang enforces -mgeneral-regs-only when used as the assembler so
this removes that flag to fix the error in #393. This is only needed for
utils_asm.S which has code saving/restoring SIMD state, but this commit applies
it to all asm files for simplicity since code for fp regs shouldn't be generated
unless they're explicitly used anyway.

The UART base has moved from the M2 chips.
Everest settings introduce some changes to unknown registers
The MCC data has changed as well.
There is a drive-by change where I discovered what some of the unknown
HID18 bits are and documented them.

On kboot, parse the ADT for SIO firmware parameters, set up the expected
data structures for SIO consumption in reserved memory, and pass those
in properties of the SIO FDT node.

Nightly is messing around with alloc_error_handler and they can't seem
to make up their mind about it, breaking our CI. Just switch to stable
rust with the usual backdoor to enable unstable features (same as the
kernel does).

Add some minimal implementation of virtio peripherals. At the level
of on-target hypervisor code we implement the MMIO layout and
maintain virtqueues. Once a buffer is available, we break into the
host proxyclient to deal with it.
Specific device-classes of the virtio spec ought to be implemented in
the proxyclient. Here the one device implemented is 9P transport,
exporting the m1n1 source directory.

This fixes m1n1 stage2 version numbers (for .tar.gz downloads) as long
as the directory name is left intact, and also supports packagers
passing their own version number if needed.

This is for things that xnu hard-codes. This first one for AGX is
required to make coprocessor TLB coherency work properly...

This code is gated behind the CHAINLOADING define. To build a
release-style m1n1 with chainloading for use with the installer
or kmutil, use:
make CHAINLOADING=1 RELEASE=1
To tell m1n1 to chainload another binary, use this var payload:
chainload=<ESP partition UUID>;<file path>
e.g.
chainload=a17b7e46-e950-bb4f-bc82-8ab1047a058e;m1n1/m1n1.bin
Closes: #154

- Hide console by default unless booting in verbose mode.
- In verbose mode, enable USB early and poll for connection before
launching payloads.
- Show console on fallback to proxy.

This turns on the system level cache. The carveout unmapping also moves
here, and now it handles T8103/T6000 properly.
