[PATCH 1/3] include: debug_ll: define puthexc_ll

[Ahmad Fatoum]

puthex_ll prints a single zero-padded unsigned long, which for a single
byte is not very readable, especially on 64-bit systems. Define
puthexc_ll() as well, which just accepts a byte and formats its nibbles
as hexadecimal characters.
