Only really needed for fbdev emulation at 8bpp. And bochs doesn't do
that. And either way bochs only does 32bit rgb, so this is all pretty
much wasted dead code.
The only consideration is that we need to not set up any gamma size
either.

Drivers shouldn't clobber the passed in addfb ioctl parameters.
i915 was doing just that. To prevent it from happening again,
pass the struct around as const, starting all the way from
internal_framebuffer_create().

Use the newly created wrapper drm_fb_helper functions instead of calling
core fbdev functions directly. They also simplify the fb_info creation.
v3:
- Don't touch remove_conflicting_framebuffers
v2:
- remove unused variable device in bochsfb_create

Make drm_fb_helper_initial_config() return an int rather than a bool so
that the error can be properly propagated. While at it, update drivers
to propagate errors further rather than just ignore them.
v2:
- cirrus: No cleanup is required, the top-level cirrus_driver_load()
will do it as part of cirrus_driver_unload() in its cleanup path.

Remove the mapping offset from the bo backing the fbdev framebuffer.
Wire up fbdev mmap function to map the backing bo using ttm_fbdev_mmap.
With that patch in place mmap(/dev/fb0) works as expected.

The final parameter to ttm_bo_reserve() is a pointer, therefore callers
should use NULL instead of 0.
Fixes a bunch of sparse warnings of this type:

To implement hotplug detection in a race-free manner, drivers must call
drm_kms_helper_poll_init() before hotplug events can be triggered. Such
events can be triggered right after any of the encoders or connectors
are initialized. At the same time, if the drm_fb_helper_hotplug_event()
helper is used by a driver, then the poll helper requires some parts of
the FB helper to be initialized to prevent a crash.
At the same time, drm_fb_helper_init() requires information that is not
necessarily available at such an early stage (number of CRTCs and
connectors), so it cannot be used yet.
Add a new helper, drm_fb_helper_prepare(), that initializes the bare
minimum needed to allow drm_kms_helper_poll_init() to execute and any
subsequent hotplug events to be processed properly.

There's no need for this to be modifiable. Make it const so that it can
be put into the .rodata section.

DRM driver for (virtual) vga cards using the bochs dispi
interface, such as the qemu standard vga (qemu -vga std).
Don't bother supporting anything but 32bpp for now, even
though the virtual hardware is able to do that.
Known issue: mmap(/dev/fb0) doesn't work.
