octeontx2-af: Add LMAC channel info to NIXLF_ALLOC response
Add LMAC channel info like Rx/Tx channel base and count to
NIXLF_ALLOC mailbox message response. This info is used by
NIXLF attached RVU PF/VF to configure SQ's default channel,
TL3_TL2_LINKX_CFG and to install MCAM rules in NPC based
on matching ingress channel number.
