Configure DSCP to Priority mapping registers so that IP precedence
field (top 3 bits of DSCP) map it to one of the 8 priority queues
for RX traffic.
Also update Priority to Thread maping to be compliant with
IEEE802.1Q-2014. Priority Code Point (PCP) 2 is higher priority than
PCP 0 (Best Effort). PCP 1 (Background) is lower priority than
PCP 0 (Best Effort).
