[PATCH 2/3] irqchip/renesas-rzg2l: Replace raw_spin_{lock,unlock} with guard() in rzg2l_irq_set_type()

From: Biju Das <biju.das.jz@bp.renesas.com>

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

While at it, add the missing cleanup.h header file.
