Add a IO block spec to use GPT backup header if primary fails.
Currently we use only the primary gpt header which is in the second
block(LBA-1) after the MBR block(LBA-0) so we restrict IO access to
primary gpt header and its entries.
But we plan to use backup GPT which is the last block of the
partition (LBA-n) in case our primary GPT header fails verification
or is corrupted.
Offset and length of the block spec will be updated runtime from
partition driver after parsing MBR data.
