armsoc: HACK: Avoid blitting and always flip
armsoc: HACK: Avoid blitting and always flip

Blitting on the exynos5 seems to show flickering on the screen.
For some reason we seem to be failing the DRI2CanFlip() check
on suspend/resume. For now force the flip path.
This is also expected to fix one more case of the fimd irq

BUG=chrome-os-partner:11708
TEST=build armsoc and loop through 50 suspend/resume cycles
