Andrew Davis 671c08ec00 ARM: mach-nspire: Rework support and directory structure
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-nspire/ 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.

Say Y here if you want to run your kernel on hardware with a
MOXA ART SoC.
The MOXA ART SoC is based on a Faraday FA526 ARMv4 32-bit
192 MHz CPU with MMU and 16KB/8KB D/I-cache (UC-7112-LX).
Used on models UC-7101, UC-7112/UC-7110, IA240/IA241, IA3341.
