clk: mmp: allow COMPILE_TEST builds

Browse Source 
The MMP clock directory is only entered for ARCH_MMP, even though the
PXA1908 and MMP2 audio clock symbols can already be selected for
COMPILE_TEST.

Add a hidden MMP clock family gate, select it from the compile-testable MMP
clock symbols, and use that symbol for the parent Makefile descent.  Keep
ARCH_MMP as the default provider for existing platform builds.

Tested with:
make LLVM=1 ARCH=loongarch drivers/clk/mmp/
