case 1:
plug in hdmi and power on, after kernel complete and before android
start(maybe can update simplification boot.img) we plug out hdmi will
appear error log.
case 2:
plug in hdmi and power on, at the beginning of drm driver bind, plug out
hdmi, the hdmi irq maybe at disable state, so the vop is in running
state which is set at uboot. in this case vop will not to enable clk
refrerence, after driver probe complete, the unused clk maybe close by
clk driver framework. this will lead to vop appear error log:
[ 4.898107] rockchip-vop ff370000.vop: [drm:vop_crtc_enable] Update mode to 720*288
[ 4.900174] rockchip-vop ff370000.vop: [drm:vop_isr] *ERROR*BUS_ERROR irq err
solution:
1. disable vop all planes before disable crtc and enable crtc;
2. disable vop all planes when can't detect connect at power on.
3. enable dma stop before detach iommu and disable dma stop after attach
iommu.

If hdmi plug in when kernel starting, hdmi may be without output.
Because the old criteria that to determine whether uboot logo is
on is hdmi phy pll locked and hdmi is connected. But in some
platform(such as rk3229), hdmi phy pll is locked even hdmi phy
is power down. In this case, the old criteria is unreliable.
So we add a new criteria that check Frame Composer register.If
the register value is not 0, we think that uboot logo is on,
hdmi has been setup.

For some reason drm driver maybe probe failed, so the drm_dev is
null. this will lead to kernel panic when enter suspend function.
