pinctrl: renesas: rzg2l: Use raw_spinlock_irqsave() on power source update

Browse Source 
The rest of the driver uses raw_spin_lock_irqsave() and
raw_spin_unlock_irqrestore() for locking.  To avoid concurrency issues
or deadlocks, use raw_spinlock_irqsave() via the scoped_guard() helper
for power source updates as well.
