octeontx2: Modify mbox request and response structures

Exact match table modification requires wider fields as it has
more number of slots to fill in. Modifying an entry in exact match
table may cause hash collision and may be required to delete entry
from 4-way 2K table and add to fully associative 32 entry CAM table.
