Cortexa32 is a 32-bit armv8a architecture processor, so set the tune feature
as armv8a instead of aarch64 which is 64-bit armv8a architecture.
It solves the following build error while compiling libgcc-initial
and libssp-nonshared.
-- snip --
aarch64-poky-linux-musl-gcc: error: unrecognized command-line option '-mfpu=neon'
aarch64-poky-linux-musl-gcc: error: unrecognized command-line option '-mfloat-abi=hard'

Current include logic goes into generic arm v8/v9 architecture tunes and
adds corresponding -march option after synthesizing it from various tune
fragments, this is fine for a machine which is using armv8/armv9 based
tunes but cortex tunes are intentionally using -mcpu option based on
selected tune value. So when cortex based default tune is selected for a
machine, it will add both -mcpu and -march to the compiler commandline
which can result in invalid combinations for this pair in gcc's own
logic. This can then result in compiler warnings/errors reporting this
e.g.
aarch64-yoe-linux-gcc -mcpu=cortex-a72.cortex-a53 -march=armv8-a+crc+crypto -mbranch-protection=standard
...
cc1: error: switch '-mcpu=cortex-a72.cortex-a53' conflicts with '-march=armv8-a+crc+crypto' switch and resulted in options '+crc+crypto' being added [-Werror]
This is seen in lot of configure test results in glibc 2.39 and the
warning is promoted to errors by gcc in some of these checks especially
with gcc-14, the logs also show it as warning in other places in
configure checks.
mcpu option will compute relevant march implicitly as it specifies a cpu
implementation and this will be the right value to use, therefore do not
specify -march when -mcpu is already describing the cpu.

Without this, the string "${PACKAGE_EXTRA_ARCHS:tune-armv8-crc}" will
show up in some bash tasks (notably opkg-arch-config.do_compile which is
how I found out about this) which will break things (besides obviously
not doing the intended thing of expanding to a list of architectures)

The crypto extension is optional for the Cortex-A73 processor, so we
shouldn't enable the crypto by default for the cortexa73 tune.
Introduce the cortexa73-crypto for the processors which do have
the cryptography unit.

We have enabled the crc extension by default for cortexa72 in patch
("tune-cortexa72: Enable the crc extension by default for cortexa72"),
then the cortexa72-crc seems redundant. So drop it. We also rename the
cortexa72-crc-crypto to cortexa72-crypto. With these changes, it will
break the BSPs which used these two tunes, but it should be easy to fix.

The crc extension is optional for the ARMv8.0 but is mandatory for the
cortexa72, so there is no reason not to enable it for the cortexa72
tune. With this change, the cortexa72-crc seems redundant. But we
had better to keep it to be compatible with the BSP which already used
that tune.

The cryptographic unit is optional for the Cortex-A72, but it was
included by default previously. This breaks building systems that
lack this functionality when using tune-cortexa72.inc.
To correct this, add a crypto entry in the tune file. Since CRC is
optional for ARMv8.0, do the same thing while we're at it.
For platforms that had been happily using tune-cortexa72.inc, a slight
degradation of performance will occur using the default. To correct
this, simply add:
DEFAULTTUNE = "cortexa72-crc-crypto"

Move all of the tune files found in conf/machine/include into their
respective architecture directories in that same location. All
references to these will need to be updated. So, change the relevant
ones for this tree in this commit as well.
For the ARM tunes, nest them one further into armv8a, armv8m, etc. and
rename some to make them uniform with the rest of the tunes.
