caif-hsi: robust frame aggregation for HSI
Implement aggregation algorithm, combining more data into a single
HSI transfer. 4 different traffic categories are supported:
1. TC_PRIO_CONTROL .. TC_PRIO_MAX (CTL)
2. TC_PRIO_INTERACTIVE (VO)
3. TC_PRIO_INTERACTIVE_BULK (VI)
4. TC_PRIO_BESTEFFORT, TC_PRIO_BULK, TC_PRIO_FILLER (BEBK)
