[igt-dev] [PATCH v2] test/gem_exec_suspend: Enable the test for discrete GPUs

["Thomas Hellström" <thomas.hellstrom@linux.intel.com>]

Discrete GPUs don't support gem_set_caching() and uses a single,
kernel provided caching mode, FIXED. Adjust the test accordingly.

This makes the test run on DG1.

v2:
- Use igt_require() do determine which of the caching mode subtests to
  run. (Petri Latvala)
- Pass the ctx parameter to igt_spin_new(), as it appears to be needed for
  the hang-SX subtests to run on DG1.
