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.
