UefiPayloadPkg:Remove x86 legacy UART defaults
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
initialization of a non-existent serial port on non legacy platforms.
