qcacmn: Fill the max 5G bandwidth from the regdomains_5g table

In the current implementation the max_5g_bw was hardcoded as 160 MHz
in reg_get_max_5g_bw_from_regdomain, as this information was not
available in regdomains_5g so far.

However, the regdomains_5g table has been updated to make the maximum
5G bandwidth supported by the regdomain available. Hence updating this
information.
