To i.MX8ULP, a PCC register provides clk(mux, gate, divider) and peripheral
reset functionality, so we need make sure the access to the PCC register
be protected to avoid concurrent access from clk and reset subsystem.

So let's use regmap here.

The i.MX specific code will be posted if this patchset is ok for you.
