amba pl011: platform data for reg lockup and glitch v2

Browse source

This patch provides platform data for following
 - uart reset function to assist uart register lockup workaround

 - init/exit function to fix glitch in the tx pin in tty_open
	when tty port0 is opened a glitch is seen in the tx line
	of uart0. This happens in pl011_startup() when tx fifo
	interrupt is provoked into asserting.
	Now uart0 pins are enabled (alt function) only when init
	is complete and turned back to gpio when closed.
