Until this point *all* displays have the same init sequence, what about
a follow-up patch that start to break things that are always the
same into helper functions?

These sequences all have a lot of the same magic bytes, so if
you guys have a datasheet for this display controller then start
adding gradually some #defines for the e0, e1, e2 etc commands
please.
