Combine block_erase*_en29lv640b and block_erase*_m29f400bt respectively
This patch combines two identical block and chip erase functions respectively:
- Merge block_erase_m29f400bt and block_erase_en29lv640b into
erase_block_shifted_jedec.
- Merge block_erase_chip_m29f400bt and block_erase_chip_en29lv640b into
erase_chip_block_shifted_jedec.
Leave their implementations in en29lv640b.c for now.
Corresponding to flashrom svn r1808.
