drm/imx: atomic phase 3 step 2: Legacy callback fixups

Browse source 
Now that we can use atomic configurations, all the legacy callbacks
of CRTCs, encoders and connectors can be switched to the atomic version.
For the imx-ldb driver, there is a clock parent setting mismatch bewteen
->enable and ->disable after the switch, so a fixup is added.  For the
imx-tve driver, since the encoder's callback ->dpms is replaced by
->disable, we need to move the setting for the IPU_CLK_EN bit(in register
TVE_COM_CONF_REG) from ->enable/->disable to ->mode_set, otherwise, the
relevant CRTC cannot be disabled correctly with a warning on DC stop timeout.
