[U-Boot] [PATCH V2 2/2] ARMV7: Fixed baudrate setting in pl01x driver

[matt.waddel at linaro.org]

From: Matt Waddel <matt.waddel at linaro.org>

The pl01x serial driver was lacking the code to switch baudrates from the
command line.  Fixed by simply saving the new baudrate and calling
serial_init() again.
