PL011: don't force baud rate of 38400 bps
The PL011 driver currently sets the baudrate to a hardcoded value of
38400 bits/second. This will break Calxeda Midway, which uses 115200
bps.
Instead don't tinker with the baud rate register at all and rely on
the firmware or bootloader setting the correct value in here.
This works fine on Versatile Express and Calxeda Midway.
