Add documentation detailing the capability for tuning the RX sampling
occasion of the Qualcomm MAC. Introduce a new flag to indicate that a
board requires switching the timing of signal sampling, instead of relying
solely on the EMAC version in the driver code. For older DTS, the logic
for current boards is hard-coded in the driver code to ensure they
function as previously.
