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.
