refactor(plat/arm): store UUID as a string, rather than ints
NOTE: Breaking change to the way UUIDs are stored in the DT Currently, UUIDs are stored in the device tree as sequences of 4 integers. There is a mismatch in endianness between the way UUIDs are represented in memory and the way they are parsed from the device tree. As a result, we must either store the UUIDs in little-endian format in the DT (which means that they do not match up with their string representations) or perform endianness conversion after parsing them. Currently, TF-A chooses the second option, with unwieldy endianness-conversion taking place after reading a UUID. To fix this problem, and to make it convenient to copy and paste UUIDs from other tools, change to store UUIDs in string format, using a new wrapper function to parse them from the device tree.
