[PATCH] pinctrl: renesas: rzg2l: use spin_{lock,unlock}_irq{save,restore}

[Claudiu <claudiu.beznea@xxxxxxxxx>]

From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>

On PREEMPT_RT kernels the spinlock_t maps to an rtmutex. Using
raw_spin_lock_irqsave()/raw_spin_unlock_irqrestore() on
&pctrl->lock.rlock breaks the PREEMPT_RT builds. To fix this use
spin_lock_irqsave()/spin_unlock_irqrestore() on &pctrl->lock.

Fixes: e1fd1f9f457b ("pinctrl: renesas: rzg2l: Configure the interrupt type on resume")
