[PATCH net-next 02/15] net: enetc: move VF message handlers to enetc_msg.c

[Wei Fang <wei.fang@nxp.com>]

Move enetc_msg_pf_set_vf_primary_mac_addr() and enetc_msg_handle_rxmsg()
to enetc_msg.c to consolidate VF mailbox message handling logic.

Make enetc_msg_handle_rxmsg() static since it's only called from
enetc_msg_task() within the same file.

This prepares for integrating enetc_msg.c into the enetc-pf-common
driver to be shared between ENETC v1 and v4 PF drivers.
