The FF-A manifest UUIDs are parsed in a function to generate the fragment for the tb fconf dts file. The UUID must have exactly 4 little endian words so that the the regex in the get_uuid function can convert into canonical format. This patch adds an assertion to catch any malformed UUID. Moreover, the bytes.fromhex() helper expects even number of bytes. It is possible that the hex string representing the little endian word could have odd number of characters. For example, 0x29a has 3 characters. This patch improves the get_uuid function to inserts 0s to the left of the parsed value (translating `29a` to `029a`), to make sure the bytes.fromhex can create an array of 4 integers.
