drivers/intel/fsp1_1: Configure UART after memory init 

FSP code will default enable the onboard serial port.
When external serial port is used, this onboard port needs to be
disabled.

Add function mainboard_after_memory_init() function to perform
required actions to re-enabled output to external serial port.

BUG=N/A
TEST=LPC Post card on Intel Cherry Hill
