qcacld-3.0: Cleanup instances of CFG_COUNTRY_CODE

Remove instances of CFG_COUNTRY_CODE and country_code from
wlan_mlme_reg struct.
Remove redundant country code APIs.

This change is needed because the country code is no longer
stored in CFG file, and subsequently, there is no need for
CFG_COUNTRY_CODE.
