[ARM] 4757/1: [AT91] UART initialization
Modify the UART initialization to allow the board-initialization code
to specify which pins are connected, and which pins should therefore
be initialized.
The current at91_init_serial() will continue to work as-is, but is
marked as "deprecated" and will be removed once the board-specific
files has been updated to use the new interface.
As in the AVR32 code, we assume that the TX and RX pins will always be
initialized.
