Register Parallel/LPC/FWH programmers the same way SPI programmers are registered

All programmers are now calling programmer registration functions and
direct manipulations of buses_supported are not needed/possible anymore.

Note: Programmers without parallel/LPC/FWH chip support should not call
register_par_programmer().

Additional fixes:
Set max_rom_decode.parallel for drkaiser.
Remove abuse of programmer_map_flash_region in it85spi.
Annotate several FIXMEs in it85spi.

Corresponding to flashrom svn r1463.
