Combine block_erase*_en29lv640b and block_erase*_m29f400bt respectively

Browse Source 
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.
