[PATCH] clk: rockchip: allow COMPILE_TEST builds

[Rosen Penev]

COMMON_CLK_ROCKCHIP already gates the Rockchip clock objects inside the
Rockchip clock Makefile.  Allow selecting it for COMPILE_TEST and use it
for the parent Makefile descent instead of ARCH_ROCKCHIP.

The per-SoC Rockchip clock symbols already have COMPILE_TEST dependencies,
so this exposes the existing build coverage to other architectures without
selecting the Rockchip platform.

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