It would be really great to not need to include these random header
files in this driver and just use raw numbers somehow. Looks like maybe
it can be done by populating a different device name from the mfd driver
depending on the version of the clk controller desired? Then that can be
matched in this clk driver and we can just put the register info in this
file?

should it be unsigned int status? Or maybe u32?

Because now this is passing -1 to unsigned int taking
regmap_update_bits()?
