No dependencies on previous patches. 5/8 adds ARCH_MMP to arm64.

It compiled without this (just Kconfig warnings), so this could go
through the appropriate sound tree as a cleanup.

Should I make it "ASoC: pxa: ..." then? SND_MMP_SOC selects SND_ARM,
which in sound/arm/Kconfig says 'Drivers that are implemented on ASoC
can be found in "ALSA for SoC audio support" section.', which confused
me about whether or not this is an ASoC compliant driver if it selects a
non-ASoC symbol.

I'm the wrong person to answer that - the symbol relies on
architecture-specific SND_ARM, and my understanding was that the code
still relies on platform data, therefore it did not seem worthwhile to
just disable inapplicable dependencies such as MMP_SRAM
(arch/arm/mach-mmp/; superseded by DT mmio-sram) or SND_ARM.
