irqchip/renesas-rzg2l: Replace raw_spin_{lock,unlock} with guard() in rzg2l_irq_set_t...

Simplify the locking logic in rzg2l_irq_set_type() by using guard(),
eliminating the need for an explicit unlock call.

[ tglx: Remove the pointless cleanup.h include. The spinlock guards come
  	from spinlock.h ]
