Subject: [PATCH] qcacld-3.0: Modify enable/disable IPA pipe for lithium dp

In case of lithium dp there is no FW interaction in RX packet
processing and is HW REO ring based. So in case of handle
first client connection and last client disconnection host
should not send HTT FW requests for pipe resume/enable at FW.
So modify the enable and disable ipa pipes host functions for
lithium dp.
