minigbm: Refactored minigbm on top a private API

Browse source 
We would like to reuse the same set of drivers for ChromeOS (with
a minigbm frontend) and Android (with a gralloc frontend).  Since
we don't want to pollute the gbm API with gralloc formats and usages,
we can refactor minigbm on top a private API that will be a superset
of gbm and gralloc.  This change redirects gbm calls to the
private API.

TEST=Ran graphics_Gbm on minnie and cyan, and checked if Chrome boots.
