[PATCH v4 2/2] clk: Allow COMPILE_TEST for subdir hisilicon in Makefile

[Tiezhu Yang]

If CONFIG_ARCH_HISI is not set but COMPILE_TEST is set, some files
in the subdir hisilicon can not be built due to CONFIG_ARCH_HISI
check in drivers/clk/Makefile.

Since the related configs in drivers/clk/hisilicon/Kconfig depend
on ARCH_HISI, so remove CONFIG_ARCH_HISI check for subdir hisilicon
in drivers/clk/Makefile.

At the same time, we should add CONFIG_ARCH_HISI and COMPILE_TEST
(for better compile testing coverage) check for the common files
in drivers/clk/hisilicon/Makefile, otherwise there exists build
failure about undefined reference.

v2:
  - Add CONFIG_ARCH_HISI check for the common files
    to fix the build failure

v3:
  - Add CONFIG_COMPILE_TEST check for the common files
    for better compile testing coverage

v4:
  - Modify the patch subject to reflect the reality
