Revert "OvmfPkg/QemuVideoDxe: Helper functions for unaligned port I/O."

Browse Source 
This reverts commit 05a5379458.

The VMWare SVGA display device implemented by Qemu (-vga vmware) uses
an I/O-type BAR which is laid out such that some register offsets are
not aligned to the read/write width with which they are expected to be
accessed. However, we reverted the initialization of VMWare SVGA device,
we don't need such unaligned I/O.
