net: Kconfig:make PHY_GIGE and individual Micrel PHYs selectable
This change migrate the following configuration options for Kconfig:
* PHY_GIGE, indicates that a controller (with an appropriate PHY) is
Gigabit capable and enables extra support in the miiutil for
parsing the status of Gigabit PHYs
* adds configuration options for Micrel KSZ9021 and KSZ9031 GbE PHYs,
which previously had to enabled through a board-specific config file

dm: core: Add device-based 'read' functions to access DT
It is common to read a device-tree property from the node associated with
a device. Add convenience functions to do this so that drivers do not need
to deal with accessing the ofnode from the device.
These functions all start with 'dev_read_' to provide consistent naming
for all functions which read information from a device's device tree node.
These are inlined when using the flat DT to save code size. The live tree
implementation is added in a later commit.

dm: core: Add operations on device tree references
Since U-Boot supports both a live tree and a flat tree, we need an easy
way to access the tree without worrying about which is currently active.
To support this, U-Boot has the concept of an ofnode, which can refer
either to a live tree node or a flat tree node.
For the live tree, the reference contains a pointer to the node (struct
device_node *) or NULL if the node is invalid. For the flat tree, the
reference contains the node offset or -1 if the node is invalid.
Add a basic set of operations using ofnodes. These are implemented by
using either libfdt functions (in the case of a flat DT reference) or
the live-tree of_...() functions.
Note that it is not possible to have both live and flat references active
at the same time. As soon as the live tree is available, everything in
U-Boot should switch to using that. This avoids confusion and allows us to
assume that the type of a reference is simply based on whether we have a
live tree yet, or not.

dm: mmc: Rewrite mmc_blk_probe()
This function is called when the MMC block device is being probed. There
is a recursive call in this function since find_mmc_device() itself can
cause the MMC device to be probed.
Admittedly the MMC device should already be probed, since we would not be
probing its child otherwise, but the current code is unnecessarily
convoluted.
Rewrite this to access the MMC structure directly.

dm: mmc: Check that drivers have operations
When binding a new MMC device, make sure that it has the required
operations. Since for now we still support *not* having the operations
(with CONFIG_DM_MMC_OPS not enabled) it makes sense to add this check.
we expect that the block devices for mmc0 and mmc1 would have device
numbers of 0 and 1 respectively.
Unfortunately this does not currently always happen. If there is another
MMC device earlier in the driver model data structures its block device
will be created first. It will therefore get device number 0 and mmc0
will therefore miss out. In this case the MMC device will have sequence
number 0 but its block device will not.
To avoid this, allow a device to request a device number and bump any
existing device number that is using it. This all happens during the
binding phase so it is safe to change these numbers around. This allows
device numbers to match the aliases in all circumstances.

It is good practice to include common.h as the first header. This ensures

Fix up some files which currently don't do this. This is necessary because
driver model will soon start using global data and configuration in the
