Edward O'Callaghan 5cff668d1a tree/: Convert printlock func ptr into enumerate values 
Converting the printlock function pointer
within the flashchip struct into enum values allows for
the flashchips db to be turn into pure, declarative data.
A nice side-effect of this is to reduce link-time symbol
space of chipdrivers and increase modularity of the
spi25_statusreg.c and related implementations.

BUG=none
TEST=ninja test.
