Subject: [PATCH v3 03/12] ath11k: modify dp_rx desc access wrapper calls inline

In data path, to reduce the CPU cycles spending on descriptor access
wrapper function, changed those functions as static inline.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1.r2-00012-QCAHKSWPL_SILICONZ-1
Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-01695-QCAHKSWPL_SILICONZ-1

The compiler does not optimise small static functions like this
automatically to inline? I'm surprised. Or are you using some really old
compiler?
