[PATCH 0/2] Enable runtime serial port debug for ArmVirtQemu

[Heyi Guo <guoheyi@huawei.com>]

These patches are based on below discussion:
https://lists.01.org/pipermail/edk2-devel/2019-March/037986.html

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.
