This claims and enables regulators listed in the simple framebuffer dt
node. This is needed so that regulators powering the display pipeline
and external hardware, described in the device node and known by the
kernel code, will remain properly enabled.

This driver uses the consumer API, so include clk.h explicitly
instead of impliclty through the provider API.

of_platform_device_create is only defined when CONFIG_OF_ADDRESS is set,
which is normally always the case when CONFIG_OF is defined, except on Sparc,
so explicitly check for CONFIG_OF_ADDRESS rather then for CONFIG_OF.

Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes, just
removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There are
some ath9k patches coming in through this tree that have been acked by
the wireless maintainers as they relied on the debugfs changes.
Everything has been in linux-next for a while.

One of the reasons for having the simplefb nodes in /chosen, and doing
explicit enumeration of the nodes there, is too allow enumerating them sooner,
so that we get a console earlier on.
Doing this earlier then fs_initcall is not useful, since the fb only turns
into a console when fbcon intializes, which is a fs_initcall too.

This claims and enables clocks listed in the simple framebuffer dt node.
This is needed so that the display engine, in case the required clocks
are known by the kernel code and are described in the dt, will remain
properly enabled.

Use the usual kernel style of goto error_foo to free resources on probe
error. This is a preparation patch for adding clocks support.
While at it also update ioremap_wc error return from ENODEV to ENOMEM.

The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.
Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.
No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.
