Subject: irqchip/irq-mvebu-gicp: Add missing spin_lock init

From: Antoine Tenart <antoine.tenart@free-electrons.com>

commit c9bb86338a6bb91e4d32db04feb6b8d423e04d06 upstream.

A spin lock is used in the irq-mvebu-gicp driver, but it is never
initialized. This patch adds the missing spin_lock_init() call in the
driver's probe function.
