Some PMICs (such as the DA9063) have non-contiguous register maps.
Attempting to read the non implemented registers returns an error
rather than a dummy value which causes 'pmic dump' to terminate
prematurely.

Fix this by allowing the PMIC driver to return -ENODATA for such
registers, which will then be displayed as '--' by pmic dump.

Use a single error code rather than any error code so that
we can distinguish between a hardware failure reading the PMIC
and a non implemented register known to the driver.

i2c: add support for offset overflow in to chip address

Signed-off-by: Robert Beckett <bob.beckett@collabora.com>

Some devices (2 wire eeproms for example) use some bits from the chip
address to represent the high bits of the offset instead of or as well
as using multiple bytes for the offset, effectively stealing chip
addresses on the bus.

Add a chip offset mask that can be set for any i2c chip which gets
filled with the offset overflow during offset setup.

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;
