Subject: [PATCH RFC 6/8] ath11k: Increase TCL data ring size

Increase TCL data ring size from 512 to 2048, this is
needed to meet 160Mhz TX throughput on WCN6750.

As the ring size is increased, there will be a slight
increase in memory used but should not impact the
functioning of any hardware.

Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-00573-QCAMSLSWPLZ-1
