Do not fallback to a fixed UART base address, otherwise it can cause
errors during initialisation of a non-existent serial port non legacy platforms.

The BaseSerialPortLib16550 does fallback to a fixed address UART defined
by PcdSerialRegisterBase and does not initialize if it is zero. Do not
assume a serial port at 0x3F8, otherwise it could cause errors during
initialisation of a non-existent serial port on non legacy platforms.

As I mentioned in the previous comments, could you please CC all UefiPayloadPkg maintainers listed in the Maintainers.txt under the root of the EDK2 directory for code changes in UefiPayloadPkg ?
Other than that, this patch looks good to me.
