a50547aca54c0e55122c32c077cab747147a6b30 hw/block/pflash_cfi02: Implement multi-sector erase
After two unlock cycles and a sector erase command, the AMD flash chips
start a 50 us erase time out. Any additional sector erase commands add a
sector to be erased and restart the 50 us timeout. During the timeout,
status bit DQ3 is cleared. After the time out, DQ3 is asserted during
erasure.
