PL011: Fix a bug in the UART FIFO polling
Sandrine Bailleux authored
Before attempting to write a character, the PL011 driver polls
the PL011_UARTFR_TXFF bit to know whether the UART FIFO is full.
However, the comparison with 1 was incorrect because
PL011_UARTFR_TXFF is not at bit 0. This patch fixes it.
