drm: add an fb creation ioctl that takes a pixel format v5

To properly support the various plane formats supported by different
hardware, the kernel must know the pixel format of a framebuffer object.
So add a new ioctl taking a format argument corresponding to a fourcc
name from the new drm_fourcc.h header file. Implement the fb creation
hooks in terms of the new mode_fb_cmd2 using helpers where the old
bpp/depth values are needed.

v2: create DRM specific fourcc header file for sharing with libdrm etc
v3: fix rebase failure and use DRM fourcc codes in intel_display.c and
update commit message
v4: make fb_cmd2 handle field into an array for multi-object formats

drm, kdb, kms: Add an enter argument to mode_set_base_atomic() API

Some devices such as the radeon chips receive information from user
space which needs to be saved when executing an atomic mode set
operation, else the user space would have to be queried again for the
information.

This patch extends the mode_set_base_atomic() call to pass an argument
to indicate if this is an entry or an exit from an atomic kernel mode
set change. Individual drm drivers can properly save and restore
state accordingly.

drm/fb: fix fbdev object model + cleanup properly.

The fbdev layer in the kms code should act like a consumer of the kms services and avoid having relying on information being store in the kms core structures in order for it to work.

This patch

a) removes the info pointer/psuedo palette from the core drm_framebuffer structure and moves it to the fbdev helper layer, it also removes the core drm keeping a list of kernel kms fbdevs.
b) migrated all the fb helper functions out of the crtc helper file into the fb helper file.
c) pushed the fb probing/hotplug control into the driver
d) makes the surface sizes into a structure for ease of passing
This changes the intel/radeon/nouveau drivers to use the new helper.
