qcacld-3.0: Fixes for IPA enablement for lithium/Hasting

Following changes were made -

- Replace #ifdef CONFIG_LITHIUM with QCA_WIFI_QCA6290 and QCA_WIFI_QCA6390
  flags. CONFIG_LITHIUM is not defined to be used within the code, the
  individual chip specific flags are defined, hence use those.

- Pass IPA enable/disable ini configuration to DP layer
