qcacmn: Add country code check for ETSI dmn

Add country code check for ETSI domain, in other words
UK, since only UK supports 6G in EU as of today. The
TPC power calculation API calls this function to check
if programmed ctry is GB to allow STA to use VLP mode.
As and when more EU countries support 6G, the checks
will be appended to this API.
