[PATCH v10 0/4] wifi: ath12k: add 11d scan offload support and handle country code for WCN7850

[Kang Yang <quic_kangyang@quicinc.com>]

This patch-set mainly does four things:
1. Add handler to send WMI_SET_CURRENT_COUNTRY_CMDID to firmware.
2. Implement 11d scan offload, and report country code to firmware by
WMI command WMI_SET_CURRENT_COUNTRY_CMDID.
3. Use WMI_SET_CURRENT_COUNTRY_CMDID to set country code for WCN7850.
4. Store country code, and update it to firmware after device recovery.

With this patch-set, WCN7850 can do 11d offload scan and update country
code to firmware successfully.

Note: This patch-set is an old patch-set in public review written by
Wen Gong. Just resend it for him.
