This chip supports erase_chip only in A/A mux mode (although the
datasheet calls it "parallel". Do we really want to have that listed?
This also applies to:
I don't think we can determine if the chip is in LPC or A/A mux mode.

erase_chip_49lfxxxc is just calling erase_sector_49lfxxxc. No need to
add it as chip erase function.
erase_chip_49lfxxc is needed to convert to block_eraser(struct flashrom
*flash, unsigned int addr, unsigned int size),
its also needed because of unlocking.
