qcacmn: Add support for NAN enable rsp in non-dbs platform

Currently, in non-dbs platforms, firmware controls NAN enable/disable.
To enable NAN in non-dbs platform, host driver sends NAN generic
request to firmware and firmware enables NAN and provides generic
response to that.
But for some legacy platforms, requires enable NAN in host.
For this, firmware adds new TLV for NAN enable response and
sends with NAN generic response. Host extracts the NAN enable
response parameters from NAN generic response packet.
