Subject: irqchip/irq-imx-gpcv2: Fix spinlock initialization

From: Tyler Baker <[email protected]>

commit 75eb5e1e7b4edbc8e8f930de59004d21cb46961f upstream.

The raw_spinlock in the IMX GPCV2 interupt chip is not initialized before usage. That results in a lockdep splat:

INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.

Add the missing raw_spin_lock_init() to the setup code.
