For systems with CONFIG_SERIAL_OF_PLATFORM=y and device_type = "serial"; property in DT of_serial.c driver maps and unmaps IRQ (because driver probe fails). Then a driver is called but irq mapping is not created that's why driver is failing again in again on request_irq(). Based on this use platform_get_irq() instead of platform_get_resource() which is doing irq_desc allocation and driver itself can request IRQ. Fix both xilinx serial drivers in the tree.
