We do not need to track the state of the IPU DI's clock flags by having each display bridge calling back into imx-drm-core, and then back out into ipuv3-crtc.c. ipuv3-crtc can instead just scan the list of encoders to retrieve their type, and build up a picture of which types of encoders are attached. We can then use this information to configure the IPU DI clocking mode without any uncertainty - if we have multiple bridges connected to the same DI, if one of them requires a synchronous DI clock, that's what we must use.
