Add initial Atmel AT49LH002 FWH/LPC chip support

Browse Source 
The chip code is untested, only one erase function out of two is currently
implemented, and unlocking/printlocking is not yet supported.

Thanks Mattias Mattsson <vitplister@gmail.com> for the initial patch!

Corresponding to flashrom svn r1434.
