ath10k: update the Rx ring fill level for wcn3990 target
The WLAN firmware writes Rx packet in the Rx ring buffer
through copy engine. The Rx ring fill level depends on
the number of mac in WLAN chipset and wcn3990 WLAN chipset
has a dual mac. Update the Rx ring buffer fill level method
to add support for wcn3990 WLAN module.
