NXP NETC is a multi-function RCiEP and it contains multiple functions,
such as EMDIO, PTP Timer, ENETC PF and VF. Therefore, add these device
IDs to pci_ids.h.

Below are the device IDs and corresponding drivers.
PCI_DEVICE_ID_NXP2_ENETC_PF: nxp-enetc4
PCI_DEVICE_ID_NXP2_NETC_EMDIO: fsl-enetc-mdio
PCI_DEVICE_ID_NXP2_NETC_TIMER: ptp_netc
PCI_DEVICE_ID_NXP2_ENETC_VF: fsl-enetc-vf

Please drop my ack.  I don't think these meet the spirit of the guidance in
pci_ids.h, which is there to minimize churn in that file and make backports
easier:

 *      Do not add new entries to this file unless the definitions
 *      are shared between multiple drivers.

PCI_DEVICE_ID_NXP2_NETC_TIMER and PCI_DEVICE_ID_NXP2_ENETC_VF
aren't used at all by this series, so they shouldn't be added to pci_ids.h.

PCI_DEVICE_ID_NXP2_NETC_EMDIO is used only by
drivers/net/ethernet/freescale/enetc/enetc_pci_mdio.c, so it should be defined
there, not in pci_ids.h.

PCI_DEVICE_ID_NXP2_ENETC_PF is used by enetc.c and enetc4_pf.c, but it looks
like those are basically part of the same driver, and it could be defined in
enetc4_hw.h or similar.
I was not aware of this, I will remove this patch, thanks.
