ARM: dts: at91: fixes dbgu pinctrl, set pullup on rx, clear pullup on tx
Remove pullup on dbgu DTXD signal, it is a push-pull output thus the pullup is pointless. Add pullup on dbgu DRXD signal, it prevents the DRXD signal to be left floating and so consuming a useless extra amount of power in crowbarred state if nothing is externally connected to dbgu.
