[PATCH net-next v2] net: fec: Add stop mode support on i.MX8DX/i.MX8QP

[PATCH net-next v2] net: fec: Add stop mode support on i.MX8DX/i.MX8QP

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Add additional machines that requires communication to the SC firmware
to set the GPR bit required for stop mode support.

NXP i.MX8DX (fsl,imx8dx) is a low end version of i.MX8QXP (fsl,imx8qxp),
while NXP i.MX8QP (fsl,imx8qp) is a low end version of i.MX8QM
(fsl,imx8qm).
