clk: spacemit: Respect Kconfig setting when building modules 



Currently, the SPACEMIT_CCU entry is only a switch for enabling entry
SPACEMIT_K1_CCU. It does not guide the build for common clock codes
even if it is a tristate entry. This makes this entry useless.

Change the Makefile to add a separate build for common clock logic,
so the SPACEMIT_CCU entry takes effect, also add necessary
MODULE_LICENSE()/MODULE_DESCRIPTION()/EXPORT_SYMBOL() for the module
build.
