wifi: ath12k: enable threaded NAPI when DP IRQ affinity is unavailable
Determine threaded NAPI policy from runtime IRQ capability of the DP MSI
IRQ.
If irq_can_set_affinity() reports that affinity cannot be set, enable
threaded NAPI for DP interrupt groups so datapath processing is not
constrained by a single-CPU softirq context.
On RB3Gen2, where IRQ affinity is unavailable in the effective IRQ path,
EHT160 UDP downlink throughput improved from 802 Mbps to 2.58 Gbps after
enabling threaded NAPI.
