octeontx2-pf: Configure VF mtu via representor
Adds support to manage the mtu configuration for VF through representor.
On update of representor mtu a mbox notification is send
to VF to update its mtu.
This feature is implemented based on the "Network Function Representors"
kernel documentation.
"
Setting an MTU on the representor should cause that same MTU
to be reported to the representee.
