qcacld-3.0: Update regulatory configs before use

Currently regulatory comnfigs are getting updated from wiphy
init inside regulatory init api which is too late in the driver
init sequence. There are some apis in driver init sequence which
uses these ini configs before wiphy init, one such example
is scm_11d_cc_db_init. since the ini configs are not populated
this may lead to undefined behaviour.

To resolve above issue, populate ini configs at the same place
where all other components inis are getting populated.
