We want to reuse this code for V3U soon. Because its RPCCKCR register is
at a different offset, the moved functions do not use the base register
as an argument anymore but the RPCCKCR register itself. Verified that an
Eagle board with R-Car V3M still works.

R-Car V3U has a CPG different enough to not be a generic Gen3 CPG but
similar enough to reuse code. Introduce a new CPG library, factor out
the SD clock handling and hook it to the generic Gen3 CPG driver so we
have an equal state. V3U will make use of it in the next patch then.
