Andrew Lunn 8fcff5f137 GPIO: mvebu-gpio: Don't initialize the mask_cache 
Due to the SMP nature of some of the chips, which have per CPU
registers, the driver does not use the generic irq_gc_mask_set_bit() &
irq_gc_mask_clr_bit() functions, which only support a single register.
The driver has its own implementation of these functions, which can
pick the correct register depending on the CPU being used. The
functions do however use the gc->mask_cache value.

The call to irq_setup_generic_chip() was passing
IRQ_GC_INIT_MASK_CACHE, which caused the gc->mask_cache to be
initialized to the contents of some random register. This resulted in
unexpected interrupts been delivered from random GPIO lines.
