soc/intel/tigerlake: Correct FSP log interface
select correct UART settings according to Kconfig
DEBUG_INTERFACE_UART: Legacy UART
DEBUG_INTERFACE_SERIAL_IO: PCH UART
Add check for DEBUG_INTERFACE_TRACEHUB selection and set
"PcdDebugInterfaceFlags" UPD accordingly.
BUG=None
TEST=boot jslrvp board with Debug FSP and check FSP UART log
