qcacmn: Find EN302_502 applicable domains from regulatory

The EN302_502 radar pattern is applicable in a predefined list of
regulatory domains (defined in DFS component). During radar table attach,
the current regulatory domain is checked if it is one of the
applicable regulatory domains.
The predefined EN302_502 applicable domains are:
ETSI11_WORLD
ETSI12_WORLD
ETSI13_WORLD
ETSI14_WORLD

Predefining these regulatory domain pair values in DFS component will
affect future regulatory updates that modify/add regulatory domains
to this list. Also, as per regulatory update #27, ETSI13_WORLD is not
EN302_502 applicable and ETSI15_WORLD is EN302_502 applicable.

Introduce a regulatory API(is_regdmn_en302502_applicable()) that finds if
the current regulatory domain pair is one of the EN302_502
applicable domains.
Modify the EN302_502 applicable regulatory domains as follows:
ETSI11_WORLD
ETSI12_WORLD
ETSI14_WORLD
ETSI15_WORLD
