qcacmn: Add 6GHz support for chan/freq/band usage in mesh mode

Currently mesh mode uses channel numbering which is derived
from APIs that don't support 6GHz channels numbering due to the
overloading of 6GHz channels with 2.4GHz and 5GHz.

Add support to obtain the correct channel number (and auxiliary
information like band and frequency) through the new APIs that
support 6GHz.
