net: dsa: microchip: lan937x: clear the POR_READY_INT status bit
In the lan937x_reset_switch(), it masks all the switch and port
registers. In the Global_Int_status register, POR ready bit is write 1
to clear bit and all other bits are read only. So, this patch clear the
por_ready_int status bit by writing 1.
