drm/i915/psr: Check for SET_POWER_CAPABLE bit at PSR init time. By moving the check from psr_compute_config() to psr_init_dpcd(), we get to set the dev_priv->psr.sink_support flag only when the panel is capable of changing power state. An additional benefit is that the check will be performed only at init time instead of every atomic_check. This should change the psr_basic IGT failures on HSW to skips. v2: Return early when SET_POWER_CAPABLE bit is 0 (Jose) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=106217 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=106346 Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180511195145.3829-2-dhinakaran.pandiyan@intel.com
