Subject: clk: qcom: common: Add API to register board clocks backwards
compatibly
We want to put the XO board clocks into the dt files, but we also
need to be backwards compatible with an older dtb. Add an API to
the common code to do this. This also makes a place for us to
handle the case when the RPM clock driver is enabled and we don't
want to register the fixed factor clock.

Subject: clk: qcom: Add support for regmap mux-div clocks
Add support for hardware that support switching both parent clocks and the
divider at the same time. This avoids generating intermediate frequencies
from either the old parent clock and new divider or new parent clock and
old divider combinations.
