Various cleanups are possible after the previous round of changes; these
have no real functional bearing other than tidying up the code.

Also, we must not call drm_helper_hpd_irq_event() until we have fully
setup the connector; keep the interrupt(s) muted until after that point.

Add core imx-drm support for hotplug connector support. We need to
setup the poll helper after we've setup the connectors; the helper
scans the connectors to determine their capabilities.

Rather than manually writing each register sequentially, we can use a

The DRM core indexes vblank by number, so there's little point
maintaining a list, and have to scan the list to find the appropriate
structure. Instead, use an array of pointers to the CRTCs.

There are a load of read-modify-write patterns to change bitfields in
various registers in this driver; provide a helper to perform this
manipulation.

gives a method by which we can try to solve this.
However, we're still stuck with trying to guess the IPU ID in the IPU
driver as we don't have a positive way to identify this. This needs to
be resolved.

When any of the components or superdevice are removed from the system,
we unbind the superdevice, thereby taking the subsystem down.
