This patch replace instances of dev_info/err/debug with
DRM_DEV_INFO/ERROR/WARN respectively inorder to use a drm-formatted

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.
drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

Noticed that everyone duplicates the same logic here and we could safe
a few lines per driver. Yay for lots of drivers to make such tiny
refactors worth-while!
v2: Forgot to git add everything :(
v3: Actually remove release_fbi (Sean, Emil, Chris) ...

Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure. I audited the drivers that
invoke this helper and I believe all of them initialize the mode_config
struct accordingly, prior to calling the fb_helper.
I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates. The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.

We get 2 warnings when building kernel with W=1:
drivers/gpu/drm/rockchip/rockchip_drm_fbdev.c:130:5: warning: no previous prototype for 'rockchip_drm_fbdev_init' [-Wmissing-prototypes]

In fact, these functions are declared
in drivers/gpu/drm/rockchip/rockchip_drm_fbdev.h,
so this patch adds missing header dependencies.

With atomic helpers there's no need to track the enabled state of a pipe
any more, because atomic helpers track this accurately already.
Just disable the early returns, since the debug checks might be useful.
v2: Don't call drm_helper_disable_unused_functions, it blows up
without this check. At least explains why rockchip still needed this
old legacy-style state tracing - to work around issues from calling
other legacy style functions!

Rockchip DRM does not yet build properly for ARM64, but we might as well
get the printf formatting correct now, to avoid the following warnings:

Use the newly created wrapper drm_fb_helper functions instead of calling
core fbdev functions directly. They also simplify the fb_info creation.
This is an effort to create a top level drm fbdev emulation option.

drm/rockchip already has support for disabling all displays on suspend
and enabling them on resume.
Disable automatic VT switching on suspend by the pm console tracking
layer.
Tested on veyron, used `echo mem > sys/power/state`
=> verified no VT switch

rockchip fixes.
* 'drm_next' of https://github.com/markyzq/kernel-drm-rockchip:
drm/rockchip: vop: power off until vop standby take effect
drm/rockchip: vop: set vop enabled after enable iommu
drm/rockchip: vop use is_enabled instead of dpms mode
drm/rockchip: vop: fix vop vsync/hsync polarity
drm/rockchip: Only alloc a kmap for fbdev gem object
In general, the data in drm/rockchip GEM objects is never accessed by
the kernel. The objects are either accessed by a GPU, by display
controller DMA, or by mmap'ing them to user space. Thus, these
buffers need not be mapped into kernel address space.
The only exception is the fbdev framebuffer(s), which may be written
in-kernel by fbcon.
