This mode is supported through hw_mode_id 7. A special mode for
IPQ8074 platform alone to bring up single pdev alone on 2G mode.
FW would advertise the mode 7 support through the WMI service
ready message and this mode will be the default mode for AP-HK10 alone.
Added a function to update the svc_id mappings for this mode as FW
requires WMI commands to be received through CE 7 for this mode.
Also adjusted the preferred mode precedence to give high precedence
to mode 7.
