qcacmn: Avoid compilation error when 6G disabled

Currently definition of wlan_reg_get_power_string is
present for 6G only which may cause compilation issue
when 6G is disabled.

Fix is to add definition of wlan_reg_get_power_string
for both 6g enable and disable case to avoid any compilation
issue.
