octeontx2-af: enable tx shaping feature for 96xx C0
Starting from 96xx C0 onwards all silicons support traffic shaping.
This patch enables that feature along with other changes
- When PIR/CIR shaping config is modified, toggle SW_XOFF
for config to take effect
- Before SMQ flush, clear SW_XOFF at all parent schedulers
- Support to read current transmit scheduler configuration via mbox
