[PATCH 08/15] drm/msm/mdp5: Set rotation property initial value to BIT(DRM_ROTATE_0) insted of 0

[ville.syrj...@linux.intel.com]

From: Ville Syrjälä <ville.syrj...@linux.intel.com>

0 isn't a valid rotation property value, so let's set the initial value
of the property to BIT(DRM_ROTATE_0) instead.

In the same vein, we must always have at leat one angle as part of
set of supported rotation bits, so let's include BIT(DRM_ROTATE_0)
in there.
