Convert various SST chips to use block_erasers

Browse Source 
Convert the following chips to block_erasers: SST28SF040A SST29EE010
SST29LE010 SST29EE020A SST29LE020 SST39SF010A SST39SF020A SST39SF040
SST39VF512 SST39VF010 SST39VF020 SST39VF040 SST39VF080 SST49LF002A/B
SST49LF003A/B SST49LF004C SST49LF008A SST49LF008C SST49LF016C SST49LF020
SST49LF020A SST49LF040 SST49LF040B SST49LF080A SST49LF160C .

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"
