[PATCH 0/2] clk: spacemit: refactor common ccu driver

The goal here is to refactor the clock driver to extract common part, and
reuse it, so in the future, we can maximize the source code usage once
adding new clock driver (specifically, for the SpacemiT K3 SoC here)

Since reset driver register via auxiliary bus which requires a adjustment
of the auxiliary device id accordingly.

This patch will depend on Kconfig fix for building modules [1], and the idea
come from K3 clock's review[2]
