drm/vc4: hvs: Make the HVS bind first 



We'll need to have the HVS binding before the HDMI controllers so that
we can check whether the firmware allows to run in 4kp60. Reorder a bit
the component list, and document the current constraints we're aware of.

/*

 * This list determines the binding order of our components, and we have

 * a few constraints:

 *   - The TXP driver needs to be bound before the PixelValves (CRTC)

 *     but after the HVS to set the possible_crtc field properly

 *   - The HDMI driver needs to be bound after the HVS so that we can

 *     lookup the HVS maximum core clock rate and figure out if we

 *     support 4kp60 or not.
