Fix no SBL serial output after restart Windows (#459)
SerialPortLib sets UART Scratch Register to a known value at the first
initialization to avoid unnecessary re-initialization afterward. But,
one of Windows driver(SIO) re-configures UART Registers while the Scratch
Register is preserved. As a result, SBL skips serial port initialization
after restarting from Windows.
Therefore, force to initialize Serial Port at Stage1A all the time simply.
