ifdtool: port the feature to set AltMeDisable/HAP bit here

Port the newest feature of me_cleaner to ifdtool
(https://github.com/corna/me_cleaner/ , Discussed in
https://github.com/corna/me_cleaner/issues/53 ) to
set AltMeDisable (or HAP for skylake/ME11) bit to the
IFD to disable ME.

In this commit I use (ifd_version >= IFD_VERSION_2) to
judge whether HAP instead AltMeDisable should be set,
since this condition is only fulfilled on skylake
or newer platforms.

This feature needs to guess ich revision, which needs
guess_ich_chipset() from flashrom to be ported here.

Routines to dump those bits are also added.
