ENGR00142551-2 IPUv3FB:Android support HW triple buffer
This patch supports HW triple buffer for IPUv3
framebuffer.
1) Remove buf ready check in EOF irq handler, as we
think the swap logic will not fail for HW triple
buffer case.
2) Sometimes HW doesn't clear buffer ready bit which
is supposed to be, so we clear it in EOF handler
to workaround it.
3) When V4L2 output/overlay are used, switch to double
buffer mode.
