We have decided to use an individual firmware UART for UEFI runtime debug, however this depends on QEMU to provide this virtual device, so we still use the OS visible system UART at the moment, with the potential *risk* of conflicting OS serial port read/write. Once QEMU implements individual firmware UART, we need rewrite PlatformGetRtSerialBase() to get the real runtime serial port base address.
