This was created by simply copying the M25PX32 block and verifying
with the M25PX16 datasheet which values needed to be changed. (The
only changes are the model_id and the 4 size-related fields).

Also, this commit sets the new M25PX16 as having write support tested,
(where the M25PX32 does not). This is after running successful write
and verify operations to 4 different M25PX16 chips with a Dediprog
SF100.
