Add functions to access addresses in the device tree. These are brought
in from Linux 4.10.
Also fix up the header guard for fdtaddr.h to avoid confusion.

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.

The of_ prefix conflicts with the livetree version of this function.
Rename it to avoid problems when we add livetree support.

This function converts the flat device tree into a hierarchical one with

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.

Add a Kconfig option to enable a live device tree, built at run time from

In linux v4.9 this returns a value. This saves checking the warning
condition twice in some code.

Sometimes it is useful to be able to find a block device without also
probing it. Add a function for this as well as the associated test.

With live tree we need a struct device_node * to reference a node. With
the existing flat tree, we need an int offset. We need to unify these into
a single value which can represent both.
Add an ofnode union for this and adjust existing code to move to this.

This function is only used in one place. It is better to just declare it
internally since there is a simpler replacement for use outside the
driver-model core code.

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.
In the end we will have:
1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree only
All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.
Note this involves changing some dead code - the imx_lpi2c.c file.

Move this group of address-related functions into a new file. These use
the flat device tree. Future work will provide new versions of these which

Currently these (board agnostic) commands cannot be selected using
menuconfig and friends. Fix this the obvious way. As part of this,
don't muddle the meaning of CONFIG_HASH_VERIFY to mean both 'hash -v'
and "we have a hashing command" as this makes the Kconfig logic odd.

Currently while setting the vsel value for dcdc1 and dcdc2
the driver is wrongly masking the entire 8 bits in the process
clearing PFM (bit7) field as well. Hence describe an appropriate
mask for vsel field and modify only those bits in the vsel
mask.

In some places we check if part_config is set to MMCPART_NOAVAILABLE
(0xff). With part_config being a char this is always false. We should
be using a u8 to store this value instead, after a quick consultation
with the Linux Kernel. Reported by clang-3.8.
