Marek Vasut e546427762 gpio: mxc: Protect GPIO irqchip RMW with bgpio spinlock 
The driver currently performs register read-modify-write without locking
in its irqchip part, this could lead to a race condition when configuring
interrupt mode setting. Add the missing bgpio spinlock lock/unlock around
the register read-modify-write.
