Hi Rob, Helge

This is resend of remain of replace of_graph_get_next_endpoint()
(In previous patch-set, media maintainer accepted some of them).
This patches are for GPU/Video, I'm not sure who should handle it.
GPU/Video maintainer as Video, or Rom as OF ?

We should get rid of or minimize of_graph_get_next_endpoint() in
its current form. In general, drivers should be asking for a specific 
port number because their function is fixed in the binding.

This patch-set replace of_graph_get_next_endpoint() by
of_graph_get_endpoint_by_regs(). There are still next_endpoint()
after this patch-set, but it will be replaced by
for_each_endpoint_of_node() in next patch-set (A)

[*] this patch-set
[o] done

	[o] tidyup of_graph_get_endpoint_count()
	[*] replace endpoint func - use endpoint_by_regs()
(A)	[ ] replace endpoint func - use for_each()
	[ ] rename endpoint func to device_endpoint
	[ ] add new port function
	[ ] add new endpont function
	[ ] remove of_graph_get_next_device_endpoint()

v1 -> v2
	- add Reviewed-by from Launrent
	- use by_regs(xx, -1, -1) for some devices
	- add extra explain for drm_of_get_dsi_bus()
	- add FIXME and Link on adv7604.c
	- based on latest of branch
