     - added API for new power management function emit_clk_levels
       This function should duplicate the functionality of print_clk_levels,
       but this solution passes the buffer base and write offset down the stack.
     - new powerplay function emit_clock_levels, implemented by smu_emit_ppclk_levels()

The eDP link rate reported by the DP_MAX_LINK_RATE dpcd register (0xa) is
contradictory to the highest rate supported reported by
EDID (0xc = LINK_RATE_RBR2). The effects of this compounded with commit
'4a8ca46b ("drm/amd/display: Default max bpc to 16 for eDP")' results
in no display modes being found and a dark panel.

For now, simply force the maximum supported link rate for the eDP attached
2018 15" Apple Retina panels.

Additionally, we must also check the firmware revision since the device ID
reported by the DPCD is identical to that of the more capable 16,1,
incorrectly quirking it. We also use said firmware check to quirk the
refreshed 15,1 models with Vega graphics as they use a slightly newer
firmware version.

1. The infinite loop causing soft lock occurs on multiple amdgpu cards
   supporting ras feature.
2. This a workaround patch to fix 6492e1b0.
   It is valid for multiple amdgpu cards of the same type.
3. The root cause is that each GPU card device has a separate .ras_list
   link header, but the instance and linked list node of each ras block
   are unique. When each device is initialized, each ras instance will
   repeatedly add link node to the device every time. In this way, only
   the .ras_list of the last initialized device is completely correct.
   the .ras_list->prev and .ras_list->next of the device initialzied
   before can still point to the correct ras instance, but the prev
   pointer and next pointer of the pointed ras instance both point to
   the last initialized device's .ras_ list instead of the beginning
   .ras_ list. When using list_for_each_entry_safe searches for
   non-existent Ras nodes on devices other than the last device, the
   last ras instance next pointer cannot always be equal to the
   beginning .ras_list, so that the loop cannot be terminated, the
   program enters a infinite loop.
 BTW: Since the data and initialization process of each card are the same,
      the link list between ras instances will not be destroyed every time
      the device is initialized.
 4. The soft locked logs are as follows:

On some OEM setups users can configure the BIOS for S3 or S2idle.
When configured to S3 users can still choose 's2idle' in the kernel by
using `/sys/power/mem_sleep`.  Before commit 6dc8265f ("drm/amdgpu:
always reset the asic in suspend (v2)"), the GPU would crash.  Now when
configured this way, the system should resume but will use more power.

As such, adjust the `amdpu_acpi_is_s0ix function` to warn users about
