[PATCH i-g-t 0/2] tests/intel/kms_sharpness_filter: Fix tap filter test failures

[Swati Sharma <swati2.sharma@intel.com>]

Fix two issues in the filter-tap subtest:

1. get_modes_for_filter_taps() could select modes requiring bigjoiner
(e.g. 7680x2160@60) for tap filter testing, but joiner + CASF is
currently unsupported. Filter out such modes using
igt_bigjoiner_possible() against the platform's max dotclock.

2. After each tap iteration, cleanup() calls igt_display_reset() which
clears the output's pending_crtc binding. Subsequent tap iterations
(e.g. tap-5 after tap-3) then fail with EIO during pipe CRC
collection because the output has no CRTC assigned. Fix by
conditionally restoring the CRTC binding via igt_output_set_crtc()
when pending_crtc is NULL.

Swati Sharma (2):
  tests/intel/kms_sharpness_filter: Skip joiner modes
  tests/intel/kms_sharpness_filter: Restore CRTC binding
