[PATCH v2 11/22] drm: Probe panels on demand

When looking up a panel through its firmware node, probe it if it hasn't

The goal is to reduce deferred probes to a minimum, as it makes it very
cumbersome to find out why a device failed to probe, and can introduce
very big delays in when a critical device is probed.
