GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in etnaviv. The only exception is gem_prime_mmap,

The gamma LUT has to be reloaded after changing the primary plane's
color format. This used to be done implicitly by the CRTC atomic_enable()
helper after updating the primary plane. With the recent reordering of
the steps, the primary plane's setup was moved last and invalidated
the gamma LUT. Fix this by setting the LUT from within atomic_flush().

Even for legacy userspace, since otherwise GETFB2 is broken and if you
switch between modifier-less and modifier-aware compositors, smooth
transitions break.

Also it's just best practice to make sure modifiers are invariant for
a given drm_fb, and that a modifier-aware kms drivers only has one
place to store them, ignoring any old implicit bo flags or whatever
else might float around.

Motivated by some irc discussion with Bas about amdgpu modifier
support.

When we swapout/in a BO we try to change the caching
attributes of the pages before/after doing the copy.

On x86 this is done by calling set_pages_uc(),
set_memory_wc() or set_pages_wb() for not highmem pages
to update the linear mapping of the page.

On all other platforms we do exactly nothing.

Now on x86 this is unnecessary because copy_highpage() will
either create a temporary mapping of the page which is wb
anyway and destroyed immediately again or use the linear
mapping with the correct caching attributes.

So stop this nonsense and just keep the caching as it is and
return an error when a driver tries to change the caching of
an already populated TT object.

This is much more defensive since changing caching
attributes is platform and driver specific and usually
doesn't work after the page was initially allocated.
