qcacld-3.0: Align Rome ini among auto platforms

Some Rome issue found on msmnile_au and sdmshrike_au, but not
found on sm6150_au, root cause is ini gap, sm6150_au 6174 ini
is got from platform: 8996AU/APQ8096 which passed CS,
can be used for msmnile_au and sdmshrike_au too.

Fixed issues like:
1. 200/s flooding unknown phy error event from F/W.
With dfsPhyerrFilterOffload=1, F/W can filter these events.

2. Ping failed from ref-sta to SAP when SAP+STA concurrency.
Roam only has 1 MAC/PHY, doesn't support dbs, can't reproduce
with gDualMacFeatureDisable=1.
Default value 6 is wrong: enable DBS for connection but disable
simultaneous scan from upper layer (DBS scan remains enabled in
FW).

3. CLean up some non-existed legacy ini.
