board: ge: bx50v3: Enable DM for PCI and ethernet
DM for PCI pulls DM for ethernet that also needs other changes described
below to build u-boot and keep existing functionality - ability to update
MAC addresses of FEC ethernet adapter and I210 adapter connected to the
Marvell switch.
- fec_mxc driver with DM needs PHYLIB;
- configuration items are moved from ge_bx50v3.h to ge_bx50v3_defconfig;
- FEC is marked as eth0 because it is always present, so indices changed:
I210 are still probed in the same order;
- board_eth_init() was used by legacy ethernet, setup for enet iomux and
pcie is moved to the board_late_init();
- pci_init() is called from the board_late_init() to initiate PCI bus
probing, so I210 devices are propagated to the device tree;
