wifi: ath12k: Remove unused tcl_*_ring configuration

Currently memory allocation for multiple hardware rings done
in host as these memory will be used by firmware/hardware.
But in case of tcl_cmd_ring and tcl_status_ring neither firmware
nor hardware uses host allocated memory and it uses memory
allocated by firmware itself. So avoid tcl_cmd_ring and
tcl_status_ring setup in host.
