qcacmn: Use best regulatory power mode in scan manager

Due to the nature of discrete channel lists for each
power mode on the host driver, it is currently not
possible to scan 6GHz channels which are not part
of the operating regulatory power mode.

To enable scanning all 6GHz channels irrespective of the
regulatory power mode (i.e., standard, low, etc.), the
existing sanity checks for the regulatory current channel
list need to refer to the super channel list
instead.

Additionally, these sanity checks need to check the
channel state and flags for the best power mode instead
of the current power mode. This will allow the scan
manager to access all 6GHz channels irrespective
of the current regulatory power mode.

Multi-band operation (for radios operable on 2.4GHz,
5GHz and/or 6GHz) is also ensured in these sanity
checks.
