clk: spacemit: extract common ccu functions

Refactor the probe function of SpacemiT's clock, and extract a common ccu
file, so new clock driver added in the future can share the same code,
which would lower the burden of maintenance. Since this commit changes the
module name from spacemit_ccu_k1 to spacemit_ccu where the auxiliary device
registered, the auxiliary device id need to be adjusted. Idea of the patch
comes from the review of K3 clock driver, please refer to this disucssion[1]
for more detail.

This change will introduce a runtime break to reset driver, and will be
fixed in follow-up commit:
ecff77f7c041 ("reset: spacemit: fix auxiliary device id")
