wifi: ath12k: advertise ieee_link_id in vdev start MLO params

Browse source 
Firmware builds the AP MLD partner profile from the hw_link_id passed in
the vdev start parameters. However, hw_link_id is not always the same as
the logical per-MLD ieee_link_id, since ieee_link_id is assigned per MLD
and not per pdev.

This matters in mixed MLO and SLO setups. For example:

  MLD 1 - 5 GHz + 6 GHz (2-link MLO): ieee_link_id 0 and 1
  MLD 2 - 6 GHz only    (1-link SLO): ieee_link_id 0
  MLD 3 - 5 GHz only    (1-link SLO): ieee_link_id 0

The same physical 6 GHz radio can use ieee_link_id 1 for one
MLD and ieee_link_id 0 for another. Pass the correct ieee_link_id to
firmware so it can build accurate per-STA profile elements.

Add ieee_link_id to wmi_vdev_start_mlo_params for the self link and to
wmi_partner_link_info for each partner link. Populate these fields in
ath12k_mac_mlo_get_vdev_args() from the corresponding vdev link_id
before encoding the WMI command.

Introduce two new flags in ML params to indicate to firmware when
the new fields are valid:

  ATH12K_WMI_FLAG_MLO_IEEE_LINK_IDX_VALID         BIT(18) for the self link
  ATH12K_WMI_FLAG_MLO_IEEE_LINK_IDX_VALID_PARTNER BIT(19) for partner links

Firmware parses ieee_link_id only when the matching flag is set.

Also fix the debug message by using correct format specifiers and host-endian
values instead of __le32 values.
