lib/hexdump: remove hexdump32 and use hexdump instead

hexdump and hexdump32 do similar things, but hexdump32 is mostly a
reimplementation that has additional support to configure the console
log level, but has a very unexpected len parameter that isn't in bytes,
but in DWORDs.
With the move to hexdump() the console log level for the hexdump is
changed to BIOS_DEBUG.
