My fault for skimming over that information in the datasheet. The
28F004S5 has a command sequence to unlock blocks; which this patch
creates unlock_28f004s5. Unlock_28f004s5 checks if the master lock isn't
set, and then initiates the Clear Block Lock-bits. This might (should ?)
be split into a printlock and unlock_28f004s5 which should only contain
Clear Block Lock-bits.
