Add macless and shared mac nodes in device trees for T4/B4

- Macless enables communication between user space config
commands and USDPAA app.
- Shared mac enables kernel and USDPAA to receive traffic from
a shared ethernet port on the basis of defined PCD rules. For T4,
fm2-mac10 is made shared node and for B4, fm1-mac10 is made
shared node.
