[PATCH i-g-t 12/23] lib/igt_fb: Require enginecopy for clear color

[Ville Syrjala <ville.syrjala@linux.intel.com>]

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

The blitter code can't currently do clear color (looks like there
is some hardware support for it in the block copy comand, but
not currently implemented). Require the use of enginecopy for
clear color modifiers.
