From: Hersen Wu <Hersenxs.Wu@amd.com>

1. Replace for_each_pipe_with_single_output with
   for_each_connected_output to avoid
   igt_display_commit_atomic return failure.

   Linux kernel AMD implementaion does not support dynamic
   allocatation for pipe connector combination. Kernel
   atomic check will return true only for one specific
   pipe connector combination, return false for other
   combinations.

2. Add eDP Rx PSR capability check psr_mode_supported.

3. Increase PSR_SETTLE_DELAY to 10 seconds.
   Measure Linux kernel AMD implementation, it will take around 8
   seconds for driver and firmmware to enter PSR1 state.
