Testing MCIMXHDMICARD on IMX53 QSRB platform revealed that the HDMI output is broken. The TVE output (even unconnected) forces the PLL4 frequency, breaking the frequency selected for the HDMI output. Fix those issue, making TVE stop grabbing the PLL4 frequency (by correctly reporting if it is unconnected).
While we are at it, fix two plane-related issues, which are now reported by DRM.
