pinctrl: baytrail: Add missing spinlock usage in byt_gpio_irq_handler
commit cdca06e4e85974d8a3503ab15709dbbaf90d3dd1 upstream.
According to VLI64 Intel Atom E3800 Specification Update (#329901)
concurrent read accesses may result in returning 0xffffffff and write
accesses may be dropped silently.
To workaround all accesses must be protected by locks.
