lcd/grey: Enable viewport fg_pattern and bg_pattern for all bitmap targets.

Greylib performed a horrible hack and stored fg and bg patterns in other
struct viewport fields. One of them was just removed. So instead of
this hack simply enable the *_pattern fields for mono targets as well,
so that greylib can use them normally.
