qcacmn: Get max 5G bandwidth from country code or regdomain pair

If the country code is present, from the country code get the country
index in g_all_countries. Then get the maximum 5G bandwidth supported
by the country. Otherwise, from the regdomain pair value, get the max
5G bandwidth that is supported by that regdomain.

One of the applications of the maximum 5Ghz bandwidth is the following:
Build the 80P80 channels only if 160 MHz bandwidth is supported by the
country
