Extend sst28sf040 to include chip and sector functions for block_eraser. Extend sst49lfxxxc to include chip, sector, block erasers functions for block_erasers. Extend sst_fwhub to include chip and sector functions for block_erasers. Add copyrights to changed files. Killed erase_sst_fwhub. Killed erase_49lfxxxc. NULL A/A mux mode full chip erasers. Ignore block locks in erase/write. Change comments from "PP mode" to "A/A mux mode" Corresponding to flashrom svn r877.
