One small step after another, the never-ending crusade towards better
code continues.

This patch makes sure that exynos drm framework handles deferred
probe case correctly.
Sub drivers could be probed before resources, clock, regulator,
phy or panel, are ready for them so we should make sure that exynos
drm core waits until all resources are ready and sub drivers are
probed correctly.
Chagelog v2:
- Make sure that exynos drm core tries to bind sub drivers only in case that
they have a pair: crtc and encoder/connector components should be a pair.
- Remove unnecessary patch:
drm/exynos: mipi-dsi: consider panel driver-deferred probe
- Return error type correctly.

When connector is created, if connector->polled is
DRM_CONNECTOR_POLL_CONNECT then drm_kms_helper_hotplug_event
function isn't called at drm_helper_hpd_irq_event because the
function will be called only in case of DRM_CONNECTOR_POLL_HPD.
So this patch sets always DRM_CONNECTOR_POLL_HPD flag to
connector->polled of parallel panel driver at connector creation.

This patch adds component framework support to resolve
the probe order issue.
Until now, exynos drm had used codes specific to exynos drm
to resolve that issue so with this patch, the specific codes
are removed.

Many drm connectors do not need mode validation.
The patch makes this callback optional and removes dumb implementations.
v2: Rebase:
- imx move to a shared (but still dummy) ->mode_valid implementation.
- probe helpers have been extracted to drm_probe_helper.c

The patch adds parallel output interface to FIMD device driver.
It also restores support for panels initialized by boot loader,
but without proper kernel driver.
Driver uses video interface bindings to find connected panel.
It uses drm_panel interface to interact with the panel.
