lib/spd: define part number in string

The part_num is defined as uint8_t[33] and we used to specify the value
as byte arrays: { 'E', 'D', 'F', 'A', '1', '6', '4', 'A', '2', ...}.

However, C compilers are smart enough to recognize and put string
literals (e.g., "EDFA164A2") into the byte array so we can rewrite as

 .part_num = "EDFA164A2MA-JD-F",

for better readability.
