Add some definitions and helpers for livetree in the main of.h header

These two functions have an of_ prefix which conflicts with naming used
in of_addr. Rename them:

The standard sandbox board cannot run the of-platdata test since it needs
SPL. Also, we should test the flat tree version of sandbox.
Add these tests to the default test script.

Update all GPIO drivers to handle the modified xlate() method.

Some tests require either livetree or flat tree. Add flags to allow the
tests to specify this. Adjust the test runner to run with livetree (if
supported) and then flat tree.
Some video tests are quite slow and running on flat tree adds little extra
test value, so run these on livetree only.

It is useful to run the driver model tests with both livetree and flat

We want to run the same test on flat and live trees. In preparation for

Running a new test should reset the sandbox state to avoid tests
interferring with each other. Move the existing state-reset code into a
function so it can be used from tests.
Also update the code to reset the SPI devices and adjust the test code to
call it.

When a live tree is being used we need to record the node that was used to
create the device. Update device_bind_with_driver_data() to support this.

When the live tree is supported some functions need to change a little.

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.

Some functions deal with structured data rather than simple data types.
It makes sense to have these in their own file. For now this just has a
function to read a flashmap entry. Move the data types also.

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.

Add a basic assortment of functions to access the live device tree. These
come from Linux v4.9 and are modified for U-Boot to the minimum extent
possible. While these functions are now very stable in Linux, it will be
possible to merge in fixes if needed.
