drm/i915: whitelist PS_(DEPTH|INVOCATION)_COUNT

drm/i915: whitelist PS_(DEPTH|INVOCATION)_COUNT

[ Upstream commit 6ce5bfe936ac31d5c52c4b1328d0bfda5f97e7ca ]

CFL:C0+ changed the status of those registers which are now
blacklisted by default.

This is breaking a number of CTS tests on GL & Vulkan :

  KHR-GL45.pipeline_statistics_query_tests_ARB.functional_fragment_shader_invocations (GL)

  dEQP-VK.query_pool.statistics_query.fragment_shader_invocations.* (Vulkan)

v2: Only use one whitelist entry (Lionel)
