Sst49lfxxxc chips are functionally the same as 82802ab chips

Browse Source 
Sst49lfxxxc software status register is functionally the same as the 
82802ab status register, "Block Protect Status"(49lfxxxc) can be treated 
the same as "Device Protect Status"(82802ab).
Erase_block_49lfxxxc is the same command sequence as erase_block_82802ab.
Add unlock_49lfxxxc to chips definitions.
Write_sector_49lfxxxc is the same as write_page_82802ab.
