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.

This is the result of automated script conversion:
scripts/contrib/convert-overrides.py <oe-core directory>
converting the metadata to use ":" as the override character instead of "_".

Uniformity clean-up, have the individual tunes reference the armv8a TUNE_FEATURES.

Move TUNECONFLICTS to the generic arm64 inc file, so that it can provide
coverage for more than just the big.LITTLE tunes.

Multiple files have " ," instead of ", " in expressions. This changes
them to conform to the way the rest of them are done.
Found and corrected via:
git ls-files | xargs sed --follow-symlinks -i 's/ ,d/, d/g'

Add CRC to the default tuning of big.LITTLE Cortex-A57-A53. This puts
it inline with all other ARMv8a tunings. Also, reference
PACKAGE_EXTRA_ARCHS_tune-armv8a-crc instead of
PACKAGE_EXTRA_ARCHS_tune-aarch64, which sets the -march to armv8 and
enables the CRC.

The setting is to modify TUNE_PKGARCH which is filled with
TUNE_PKGARCH_64 or TUNE_PKGARCH_32 in arm-arch64.inc
This lets higher up tune files for arm64 SOCs override them if needed,
this can help building multiple armv8 machines with different tunes in
same workspace.
No need to set TUNE_PKGARCH in tune files as it is synthesized from ARMPKGARCH
Add ARMPKGARCH for aarch64 tunes

Now that they uses -mcpu, its better to have tune specific build
directories, since aarch64 wont be appropriate any longer

mcpu is more appropriate on aarch64 and generates more optimized code
forr a given SOC, unlike -march/-mtune combination as decribed here [1]

commit 3613b2780a6b5d5d70ea6802be5060a8214cbdb5 from
git://github.com/renesas-rcar/meta-renesas
The renesas rcar SoC H3/M3 is big.LITTLE architecture(cortex-a57.cortex-a53).
In order to optimize the performance of the code running on SoC H3/M3,
add a tune file for ARM Cortex-A53-Cortex-A57.
Create this tune file by refering GCC doc, 3.18.5 ARM Options.
