Add minimalegl QPA platform plugin
The EGLFS platform plugin was originally meant to be an example and thus to be kept simple. However, EGLFS is becoming more and more complex with the addition of hooks for board support, cursor integration, built-in evdev support etc. minimalegl is a new platform plugin that intends to follow the original intentions of EGLFS. The code is an adaptation of EGLFS as of f913859f8 Change-Id: I3d4cf84cde380cdcc7e0e8bfefff4df6be731b8d Reviewed-by: Jørgen Lind <jorgen.lind@nokia.com>
