Currently in driver doing memory allocation for tx_monitor,
tcl_cmd_ring and tcl_status ring. Here driver support for
tx_monitor mode is not there and memory for tcl_cmd and tcl_status
rings are allocated by firmware and it uses that memory instead of
host allocated. So avoid these unused ring setup configuration.

2.34.1
Currently in ath12k_dp_tx_htt_monitor_mode_ring_config()
ath12k_dp_tx_htt_tx_monitor_mode_ring_config() function wrongly called twice.
Fix that by calling ath12k_dp_tx_htt_rx_monitor_mode_ring_config().
Currently monitor mode is disabled in driver so the change is compile
tested and boot sequence verified.

Currently tx monitor is not supported in driver.So remove
the tx monitor ring configuration, allocation and handling.

It nice to see code removal in general :)
But I've also seen some concerns internally around code removal
especially when the code will have to be re-added in future while
properly supporting the feature. I guess the cover letter
may need to clarify those concerns at least for internal review.
Other than that, the series LGTM

Looks like you modifying in wrong place because the debug log
information is not matching the rx message. no ?

This is mainly to avoid unnecessary memory allocation for the unused rings.
And this can be added in the future while enabling the feature.

I agree. I think I somehow overlooked the memory optimization part. Thanks
for the clarification.
