libpayload: Add minimal support for PL011 UART
This creates a new PL011 config variable which avoids the
infinite busy wait on serial_putchar() because the register
mapping is not compatible with current implementation.
BUG=None
BRANCH=none
TEST=printf() works on the PL011 based ARMv8 foundation model
