Now that we have moved to generic phy based bindings,
we don't need to have any code related to older dptx-phy.
Nobody is using this dptx-phy anymore, so removing the
same.

exynos_dsi_display is used by internal Exynos DRM framework for
representing pair encoder->connecter. As it should be mapped 1:1 to dsi
private context it seems more reasonable to embed it directly
in that context. As a result further code simplification will be possible.
Moreover it will be possible to handle multiple DSI devices in the system.

The patch replaces separate calls to driver (de)registration by
loops over the array of drivers. As a result it significantly

This patch fixes null pointer dereference issue incurred
when ipp driver is enabled and Exynos drm driver is closed.
Non kms driver should register its own sub driver to setup necessary
resources, which is done by load(). So null pointer dereference
occurs when ipp driver is enabled and Exynos drm driver is closed
because ipp core device is registered after component_master_add_with_match
call.
This patch makes exynos_drm_device_subdrv_probe() to be called after all non
kms drivers are registered.

This patch fixes a null pointer dereference issue incurred by
calling g2d_remove when exynos_drm_platform_probe is failed.
cmdlist_pool of g2d is allocated when g2d sub driver is probed.
So if exynos_drm_platform_probe is failed, the g2d sub driver is
not probed and the cmdlist_pool is still NULL.

It happens on occasion that developers of generic user-space applications
abuse the dumb buffer API to get hold of drm buffers that they can both
mmap() and use for GPU acceleration, using the assumptions that dumb buffers
and buffers available for GPU are
a) The same type and can be aribtrarily type-casted.
b) fully coherent.
This patch makes the most widely used drivers warn nicely when that happens,
the next step will be to fail.
