Strago: Support common code

Update the strago code to use the common romstage.c code.  The PEI_DATA
structure is passed in as a pointer in romstage_params.  Use the common
UART initialization routine name.

BRANCH=none
BUG=None
TEST=Build and run on strago
Test is successful if post code is 0x35.

Post code of 0x37 indicates that the FSP binary is broken, not properly
returning the necessary HOBs!  Workaround is to disable
CONFIG_DISPLAY_HOBS in config.strago.
