Subject: [PATCH ath-next 0/9] wifi: ath12k: support MLO for WCN7850

WCN7850 firmware uses API-1 so it can not advertise MLO support via
firmware IE, but instead it uses single_chip_mlo_support flag in QMI
message, the first three patches serve for this purpose.

Currently ml_arg->assoc_link flag is not set in
WMI_VDEV_START_REQUEST_CMDID, this result in WCN7850 firmware crash
in MLO case, so patch [04/9] sets it for assoc link.

Patch [05/9] makes sure we do assoc for assoc link before any other
links, as requested by WCN7850 firmware.

Patch [08/9] change to send REO queue configuration to firmware
for all links including non-primary link. For that purpose, preparation
is done in patch [06,07/9].

The last patch increases number of different channels to 2 for single
pdev device, to avoid failing in bringup the second link.
