ARM: SPEAr: DT: add uart state to fix warning
amba-pl011 driver supports two pin state "default" and "sleep" and it expect from dt to provide this pinctrl states and phandler otherwise it gives a warning message. To remove this warning message pass default state with null phandler to uart pins in device node (In our case all the pins are configured in default states so we pass null phandler to pins).
