clk: cdce925: simplify using devm_regulator_get_enable()

Simplify the driver using devm_regulator_get_enable() instead of
open-coding the devm_add_action_or_reset().

A (minor?) functional change is that we don't print an error in case of a
deferred probe. Now we also print the error no matter which of the
involved calls caused the failure.
