Use maximum width between 2 edges to setup spdifin thresholds and detect the input sample rate. This comes from Amlogic SDK and seems to be marginally more reliable than minimum width.
This is done to align with a future eARC support. No issue was reported with minimum width so far, this is considered to be an update so no Fixes tag is set.
