drm/i915: Add bigjoiner and uncompressed joiner hw readout sanity checks

Browse source

Add sanity checks for primary and secondary bigjoiner/uncompressed
bitmasks, should make it easier to spot possible issues.

v2:
-Streamline the expected masks and add few more drm_WARNs. (Ville)
-Use %#x format specifier for printing joiner masks. (Ville)
-Use struct intel_display instead of struct drm_i915_private. (Ankit)

v3:
-Rename helper to get expected uncompressed joiner pipes. (Ville)
