MIPS does not always provide clk*() interfaces and there are no
always-present stubs for them, so depending on "MIPS || COMPILE_TEST"
is not strong enough to prevent build errors.
Likewise MACH_INGENIC_SOC || COMPILE_TEST is not strong enough
since if only COMPILE_TEST=y (with some other MIPS MACH_ or CPU or
BOARD setting), there are still the same build errors.
It looks like depending on MACH_INGENIC is the only thing that is
sufficient here in order to prevent build errors.

v2: use MACH_INGENIC instead of MACH_INGENIC_SOC (thanks, Paul)

Say yes here to build support for the Ingenic JZ47xx SoCs ADC unit.
