intel: properly test for HAS_LLC

If the kernel supports the test, we need to check the param.
Copy&pasta from the above checks that only look at the return value.
Interesting how much one can get such a simple interface wrong.

    intel: query for LLC support

Patch even claims to have fixed this in v2, but is actually unchanged
from v1.

radeon: fix stencil miptree allocation of combined ZS buffers on EG and SI

This allows texturing with depth-stencil buffers directly without the copy
to CB. The separate miptree description for stencil is added, because
the stencil mipmap offsets are not really depth offsets/4 (at least
for the texture units).

missed slightly and in effect had no effect on the outcome of checking
whether the kernel/chipset supported LLC.

configure.ac: Allow forcible disabling of Cairo support

We don't want to build libdrm tests with Cairo support under Poky, since
they're never used and also cause a build loop from libdrm -> cairo ->
mesa-dri -> libdrm.

To avoid variance in build results, introduce a --disable-cairo-tests
switch.

initialize width/height fields in drmModeCrtc

If we have valid timings, we can at least set width/height to
*something*, which is I think at least less confusing than always
seeing width/height of zero.  At least modeprint and modetest
seem to expect width/height to mean something.
