v2 cover Remove some unneeded arm/mach- dirs

Hello all,

This series removes some of the unneeded arm/mach-* dirs for reasons described in the patches. Adding this cover letter to keep track of version changes in one place.

Thanks,
Andrew

Changes from v1:
- Drop two patches that cannot be verified to not change behavior
- Update commit message to include l2c_aux_mask info

PATCH v2 1/8 ARM: Kconfig: move platform selection into its own Kconfig file

Mostly just for better organization for now. This matches what is done on some other platforms including ARM64. This also lets us start to reduce the number of mach- directories that only exist to store the platform selection.

Start with "Platform selection" and ARCH_VIRT.

PATCH v2 6/8 ARM: mach-airoha: Rework support and directory structure

In reply to Andrew Davis

Having a platform need a mach-* directory should be seen as a negative, it means the platform needs special non-standard handling. ARM64 support does not allow mach-* directories at all. While we may not get to that given all the non-standard architectures we support, we should still try to get as close as we can and reduce the number of mach directories.

The mach-airoha/ directory, and files within, provide just one "feature":
having the kernel print the machine name if the DTB does not also contain a "model" string (which they always do). To reduce the number of mach-* directories let's do without that feature and remove this directory.

It also seems there was a copy/paste error and the "MEDIATEK_DT" name was re-used in the DT_MACHINE_START macro. This may have caused conflicts if this was built in a multi-arch configuration.

NOTE: The default l2c_aux_mask is now ~0 but these devices never have this type of cache controller so this is safe.

PATCH v2 7/8 ARM: mach-sunplus: Rework support and directory structure

In reply to Andrew Davis

The mach-sunplus/ directory and files, provides just one "feature":
having the kernel print the machine name if the DTB does not also contain a "model" string (which they always do). To reduce the number of mach-* directories let's do without that feature and remove this directory.

NOTE: The default l2c_aux_mask is now ~0 but these devices never have this type of cache controller so this is safe.
