[PATCH 1/5] ath10k: add 10.2.4 firmware support

[Rajkumar Manoharan]

10.2.4 firmware uses bitmask in wmi_resource_config to configure
10.2 firmware features like airtime fairness and rx batch mode instead
of maintaining separete bool entry. This allows new features that can be
configure during init time without breaking backward compatibility.
