[Why & How]
Additional debug flags that can be useful for testing USB4 DP
link training.

Add flags:
- 0x2 : Forces USB4 DP link to non-LTTPR mode
- 0x4 : Extends status read intervals to about 60s.

[Why]
To process SET_CONFIG transactions with DMUB using inbox1 and
outbox1 mail boxes.

[How]
1) Added inbox1 DPIA command subtype DMUB_CMD__DPIA_SET_CONFIG_ACCESS to
   issue SET_CONFIG command to DMUB in dc_process_dmub_set_config_async().
   DMUB processes the command with DPIA sends reply back immediately or
   in an outbox1 message triggering an outbox1 interrupt to driver.
2) DMUB posts SET_CONFIG reply as an Outbox1 message of type
   DMUB_OUT_CMD__SET_CONFIG_REPLY.
3) The dmub async to sync mechanism for AUX is modified to accommodate
   SET_CONFIG commands for both command issue and reply code paths.

[WHY]
To add support for HPD & HPD RX interrupt handling for USB4 DPIA in
YELLOW_CARP_B0. USB4 DPIA HPD & HPD RX interrupts are issued from DMUB to
driver as a outbox1 message.

[HOW]
1) Created get_link_index_from_dpia_port_index() to retrieve link index
   from dpia port index for HPD & HPD RX dmub notifications.
2) Added DMUB HPD & HPD RX handling in dmub_srv_stat_get_notification().
