imx-drm: ipuv3-crtc: change display enable/disable order

Browse source

Now that ipu_dc_disable_channel correctly waits for the channel to finish,
we can reorder the enable/disable order to first stop the DC and DI and
only then disable the IDMAC. Enabling is done the other way around: IDMAC
first, then DC, then DI.

This avoids an issue where sometimes the channel would not correctly start,
leading to non-working LVDS displays.
