Generify jedec functions by introducing an address mask
The patch converts jedec functions into mask-based generics which can
be used for many chip provided the only changes are the addresses are
converted from 0x5555/0x2AAA to 0x555/0x2AA or similar.
The patch mostly changes jedec.c, but a few other files are changed
because they use the jedec functions within their own functions.
The patch also adds a copyright line to flashchips.c because of my
recent work in converting AMD and Atmel chips to use struct erase_block.
Corresponding to flashrom svn r828.
