tools/firmware-utils: remove hardcoded values from mktplinkfw2.c

Browse source 
This patch removes all the hardcoded board-specific values from
mktplinkfw2.c, and as well as the corresponding support code.

By design, this change also deletes all of the broken matching logic
that was embedded in mktplinkfw2 and aligns the "inspect" behavior
with that of mktplinkfw (i.e. print the parsed header content as
they are without further processing).
