MLK-17144 driver: soc: use mutex for power domain of imx8mq In current gpc-psci.c file, the irqchip driver and gpc power domain driver use the same spinlock to prevent concurrent access to the GPC module. But actually, the irq and power domain are two seperated function and controlled by different registers. when using the same spinlock for these two funcition, in some corner case the system will be deadlock if the spinlock is already acquired by the power domain, but the power domain on/off is interrupted by timer IRQ. So adding a mutex for power domain driver. Signed-off-by: Bai Ping <ping.bai@nxp.com> Reviewed-by: Anson Huang <Anson.Huang@nxp.com>
