GPU error dump contained all module parameters. If we are moving
display parameters to intel_display_params.[ch] they are not dumped
into GPU error dump. This patch is adding moved display parameters
back to GPU error dump. Display parameters are also included in
i915_capabilities
v2: Add parameters to i915_capabilities as well
