Right now the ARM Platform driver does not do much, but
I expect to move most platform specific code into platform
specific driver in the future.

v5:
- ensure / document that the VIRTIO_BLK_DEVICE_PATH structure must be
packed
- fix whitespace damage in definition of "mVirtioBlockDevicePath"
- the platform driver is added to all platform DSC and FDF files in the
previous patch; this patch focuses on virtio only
