Subject: [net-next PatchV2 1/4] octeontx2-af: CN10KB: Add USGMII LMAC mode

Upon physical link change, firmware reports to the kernel about the
change along with the details like speed, lmac_type_id, etc.
Kernel derives lmac_type based on lmac_type_id received from firmware.

This patch extends current lmac list with new USGMII mode supported
by CN10KB RPM block.
