Various JEDEC refactorings touching 82802ab.c, sharplhf00l04.c and stm50flw0x0x.c

Rename print_82802ab_status to print_status_82802ab add unlock_82802ab strip unlock code from erase_block_82802ab rename erase_82802ab_block  to erase_block_80280ab delete sharplhf00l04.o from Makefile delete *_lhf00l04* from chipdrivers.h.

add unlock_stm50flw0x0x
delete wait_stm50flw0x0x
delete write_page_stm50flw0x0x
convert erase_stm50flw0x0x to erase_chip_stm50flw0x0x
delete write_stm50flw0x0x
add unlock_82802ab to two Intel chips with TEST_BAD_WRITE
change the status of 82802AB, 82802AC, M50FW040, M50FW080 to TEST_OK_PR

Corresponding to flashrom svn r948.
