When opening a DRM debugfs file, locate the right path based on the
given DRM device FD.
This is needed so, in setups with more than one DRM device, any
operations on debugfs files affect the expected DRM device.
v2: - rebased and fixed new API additions
v3: - updated chamelium test, which was missed previously
- use the minor of the device for the debugfs path, not the major
- have a proper exit handler for calling igt_hpd_storm_reset with the
right device fd.

Rename these properties to have them use the same naming convention
as the igt_*_t structs.

Add an index property which helps accessing the corresponding
igt_plane_t structure through the igt_*_get_plane() functions.

Testcase for plane visibility after atomic modesets. The idea of the test
is the following:
- draw a blue screen with high resolution
- enable a yellow plane, visible, in lower-left corner
- set a new lower resolution mode (1024x768) that makes plane invisible
- check from debugfs 'i915_display_info' that the plane is invisible
- switch back to higher resolution mode
- check from debugfs 'i915_display_info' that the plane is visible again
- repeat number of iterations, default 64
v2: allow test to be run on non-Intel drivers (Daniel)
moved test for plane visibility to as helper function (Daniel)
moved get_vblank() function to be part of helper functions (Daniel)
rename 'tiling' parameter as 'modifier' (Daniel)
select a mode from a list so that the plane should be invisible.
use default 1024x768 mode only as a fallback if decent mode has not
been found (Daniel)
add tiling MODE_NONE (Daniel)
v3: draw as many overlay planes as the platform supports + cursor plane
on top of each other on lower-left corner
skip the test if i915_display_info file is not available
test plane visibility with igt_assert_plane_visibility() function
drop option for multiple test iterations (Daniel Vetter)
v4: switch 'for_each_connected_output()' to
'for_each_valid_output_on_pipe()'
skip Y and Yf tiling for generations older than 9 (Maarten)
