OVMF: Add Block MMIO protocol definition

Browse Source 
This protocol is similar to the standard UEFI BlockIo protocol,
except it has no function calls and simply defines a base address
in memory where reads & writes for the block device should occur.

One planned usage is to fill a memory region with a small disk
image, and allow it to be used as a normal disk by the
standard drivers.
