Komeda uses the component framework, which does open/close a new
devres group around all the bind callbacks. Which means we can use
devm_ functions for managing the drm_device cleanup, with leaking
stuff in case of deferred probes or other reasons to unbind
components, or the component_master.
Also note that this fixes a double-free in the probe unroll code, bot
drm_dev_put and kfree(kms) result in the kms allocation getting freed.
Aside: komeda_bind could be cleaned up a lot, devm_kfree is a bit
redundant. Plus I'm not clear on why there's suballocations for
mdrv->mdev and mdrv->kms. Plus I'm not sure the lifetimes are correct
with all that devm_kzalloc usage ... That structure layout is also the
reason why komeda still uses drm_device->dev_private and can't easily
be replaced with a proper container_of upcasting. I'm pretty sure that
there's endless amounts of hotunplug/hotremove bugs in there with all
the unprotected dereferencing of drm_device->dev_private.

1. Drop komeda-CORE product id comparison and put it into the d71_identify
2. Update pipeline node DT-binding:
(a). Skip the needless pipeline DT node.
(b). Return fail if the essential pipeline DT node is missing.
With these changes, for chips in same family no need to change the DT.
v2: Rebase
