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