ASoC: ti: ams-delta: Allow it to be test compiled

The driver is now built only when MACH_AMS_DELTA is selected, which
requires a very specific selection of ARCH settings.  As a consequence, it
gets very little attention from build-bots, if not none.

Drop the driver dependency on <asm/mach-types.h>, no longer required since
conversion to snd_soc_register_card() and drop of machine_is_ams_delta().
With that in place, allow the driver to be built in any environment as
long as COMPILE_TEST is selected.  Take care of not selecting
SND_SOC_OMAP_MCBSP if COMMON_CLK is not selected.
