Issue 884: Proper integration of the TILER rotation

Reported by Michael Mrozek, Jun 14, 2018

The current TILER rotation-code used in the Pyra was just a quick 
hack to get it to work.
It causes some issues (as far as I am aware because of this we can't 
use the 3D driver and omapdrm also doesn't work properly), so it 
needs to be cleaned up for release.

Key problem is defining the drm_fb_helper to request rotation.
There seem to be mechanisms in the DRM work queue that a panel 
(driver) can define the panel orientation.

With kernel 5.3-rc1 there have been changes to drm_fb_helper.c which 
breaks our framebuffer rotation again :(
