From: Harsh Kumar Bijlani <quic_hbijlani@xxxxxxxxxxx>
WLAN Host driver interacts with the Firmware and vice versa using
Host-To-Target (HTT) interface.
HTT interface code is spread across multiple files (ex dp_tx.c, dp_rx.c
etc) and this interface is independent of the underlying architecture Tx
and Rx. Relocate HTT specific code from dp_rx.c to newly introduced file
dp_htt.c for HTT interface. This new file is compiled as part of the
common module ath12k.ko.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
