To access/read the lock bits, we use the same mode to read the chip id.

This patch looks into the write situation for the Intel 28F001BX-{B,T}. 
Looks like they're just a 82802ab page write.

Unlock_28f004s5 has been changed to read all the lock bits and if at 
least one of the block lock bits are set, clear them all. If the master 
lock bit is set, we can't do anything about it, so we return.
