drmmode_display.c :Exynos: Fix the flicker issue in HW cursor

To enable the overlay for HW cursor layer a specific ioctl need to
be called. This Ioctl will set the postion of layer and thus calling
chroma keying, which is required for overlay.

BUG=Flicker in browser tab is being observed which I guess
	is in x86 too
TEST=Tested on Daisy with xorg.conf having HWCursor "true"
