John Madieu 3b0cf6ab35 pinctrl: renesas: rzg2l: Refactor OEN register PWPR handling 
Extract the OEN register write with PWPR protection logic into a helper
function to eliminate code duplication between rzg2l_write_oen() and
rzg2l_pinctrl_resume_noirq().

Introduce rzg2l_oen_write_with_pwpr() helper that encapsulates the
PWPR unlock, OEN register write, and PWPR lock sequence. This helper
must be called with pctrl->lock already held by the caller.
