switch default hwc from TI to DRM

Default TI hwcomposer is replaced with DRM hwcomposer.
Reason - TI hwc is not working properly (the home screen
is not loading).

Features missing for DRM HWC at the moment:
 - dual display support;
 - HDMI hotplug.

These features are expected in nearest future.

To turn on TI hwcomposer instead of DRM one - set
flag USE_TI_HWC=y during the build.
