drm_color_ctm_3x4 is some undocumented amgdpu private
uapi and thus has no business being in drm_mode.h.
At least move it to some amdgpu specific header, albeit
with the wrong namespace as maybe something somewhere
is using this already?

As evidenced by in-field reports, this panel shipped on pompom but we
never added the ID and thus we're stuck w/ conservative timings. The
panel was part of early patches but somehow got left off in the
end. :( Add it in now.

For future reference, EDID from this panel is:
	00ffffffffffff002c82121200000000
	321e0104951a0e780ae511965e55932c
	19505400000001010101010101010101
	010101010101a41f5686500084302820

	004b443131364e3039333041313600f6

We use the ASCII string from decoding the EDID ("KD116N0930A16") as
the panel name.

Add an fbdev emulation for SHMEM-based memory managers. The code is
similar to fbdev-generic, but does not require an additional shadow
buffer for mmap(). Fbdev-shmem operates directly on the buffer object's
SHMEM pages. Fbdev's deferred-I/O mechanism updates the hardware state
on write operations.

The memory pages of GEM SHMEM cannot be detected by fbdefio. Therefore
fbdev-shmem implements the .get_page() hook in struct fb_deferred_io.
The fbdefio helpers call this hook to retrieve the page directly from
fbdev-shmem instead of trying to detect it internally.

Add a callback for drivers to provide framebuffer pages to fbdev's
deferred-I/O helpers. Implementations need to acquire a reference on
the page before returning it. Returning NULL generates a SIGBUS
signal.

This will be useful for DRM's fbdev emulation with GEM-shmem buffer
objects.
