libpayload: Change "GPIOs" into flags.
Some constants which were used to interpret the contents of the coreboot
tables were moved to the appropriate libpayload header file. The constant which
describes the maximum length of a GPIO name was renamed to have a CB_ prefix.
That makes it more obvious what sort of GPIO name it describes, and reduces the
change of a name collision. It also makes it more consistent with other names
in that header, although some other exceptions still exist.
