net: dsa: bcm_sf2: Prevent GPHY shutdown for kexec'd kernels
For a kernel that is being kexec'd we re-enable the integrated GPHY in order for the subsequent MDIO bus scan to succeed and properly bind to the bcm7xxx PHY driver. If we did not do that, the GPHY would be shut down by the time the MDIO driver is probing the bus, and it would fail to read the correct PHY OUI and therefore bind to an appropriate PHY driver. Later on, this would cause DSA not to be able to successfully attach to the PHY, and the interface would not be created at all.
