[PATCH] clk: hisilicon: allow COMPILE_TEST builds

[PATCH] clk: hisilicon: allow COMPILE_TEST builds

[Rosen Penev]

The HiSilicon clock symbols already depend on ARCH_HISI or COMPILE_TEST,
but the parent clock Makefile only descends into the hisilicon directory
when ARCH_HISI is enabled.

Add a hidden family gate selected by the HiSilicon clock and reset symbols,
default it for ARCH_HISI, and use it for the parent Makefile descent.  This
keeps existing platform builds unchanged while allowing compile-test
coverage.

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