enic: Add support for new fw devcmds for port profile handling 

This patch introduces new fw devcmds for port profile handling.
These new commands are similar to the current fw commands for
port profile handling. The only difference being that the new
commands split the existing port profile handling devcmds into multiple
fw commands, giving the driver finer control over port profile operations.
