[PATCH v4 0/2] clk: spacemit: Fix module build for spacemit common ccu driver

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.

This patch mostly fix the build problem, and it should serve as a
basic for the incoming K3 clock driver. See link.

Change from v3:
1. patch 1: change Makefile to trigger module build actually
2. patch 2: new patch for remove internal Kconfig entry

Change from v2:
1. change namespace name to CLK_SPACEMIT

Change from v1:
1. Use EXPORT_SYMBOL_NS_GPL to export clock ops

Inochi Amaoto (2):
  clk: spacemit: Respect Kconfig setting when building modules
  clk: spacemit: Hide common clock driver from user controller
