It seems to be no objection so far against my last suggestion to
use regmap's mmio_clk() for named ipg clk only. So you may still
consider about that.

Anyway, I'd like to do thing in parallel. So I just simply tested
it on my side and its works fine, it may still need to be tested
by others though.
