feat(gpt): validate CRC of GPT partition entries
While loading partition entries, calculate CRC using tf_crc32() for each
entry to find the full CRC value of the partition entry array.
The start of the GPT partition entry array is located at the LBA
indicated by the partition entry array LBA field in the GPT header. The
size of the partition entry array is indicated by the size of partition
entry multiplied by the number of partition entries.
Compare the calculated CRC with the partition entry array CRC in the GPT
header, error out if the values do not match.

feat(partition): add interface to init gpt
Current interface 'partition_init' accepts parameter image_id
and returns no value. But the entire partition driver is build
only to parse and handle GPT partitions, so add new interface
gpt_partition_init which would return failure to platform code
if it fails to parse the image.

refactor(partition): convert warn to verbose
Convert all warn messages to verbose messages. As most warning are
needed during debug only and and won't increase the binary size by
default.

feat(partition): add support to use backup GPT header
Currently we just use primary GPT header which is located in second
entry after MBR header, but if this block is corrupted or CRC
mismatch occurs we could try to use the backup GPT header located at
LBAn and GPT entries following this from LBA-33.
Add suitable warning messages before returning any errors to identify
the cause of issue.

feat(partition): add a function to identify a partition by GUID
With the GPT partition scheme, a partition can be identified using
it's UniquePartitionGUID, instead of it's name. Add a function to
identify the partition based on this GUID value. This functionality is
useful in identification of a partition whose UniquePartitionGUID
value is known.
