The qcom clk driver has support for the 'regmap' clk_hws and the
non-regmap based clk_hws. I suggest having a list of clk_hw pointers
that you register in a loop and then have other lists that you use to
register wrapper structs, etc. Otherwise we're left with a bunch of code
that's copy/pasted around.
