This adds a function to register the cpws device and another one
to register the MAC addresses provided by the am33xx.

The process of unflatten the device tree is known from the kernel,
so rename the function, because that's what it does.

- Add missing prototype for of_free()
- When root node is freed set root_node to NULL
- (re)scan aliases after freeing a node. This is necessary because
the freed node may be an alias or point to an alias

With bootm of_fix_tree() will already be called from the generic bootm
code, so do not do this again in the Android image handler.

When of_find_node_by_path is called with a non existing path we
return just some node. return NULL instead.

Currently the bootm code uses of_fix_tree to apply the fixups
to the devicetree given on the command line. This function assumes
that there is enough space for the fixups available. Also on ARM
we have to make sure the tree does not cross 1Mib boundaries.
This patch moves the space allocation and alignment ensurance
to of_get_fixed_tree and uses it in bootm. This is the first
step for making of_get_fixed_tree the single point of devicetree
handling in barebox.
of_get_fixed_tree now takes an argument of the input fdt. If it is
given, this one is used, otherwise an internal oftree is used which
will be created in subsequent patches.

The am33xx hsmmc controller is actually a omap4 type controller which
means that it has a 0x100 offset in the registers.

Both include/string.h and include/stringlist.h define the c preprocessor macro
__STRING_H. This leads to a compile time error, in case both files are
(indirectly) included.

Only the OMAP4 has a register offset of 0x100 in the register space. Fix
this by using the device id mechanism. This became broken when the device
register convenience functions were introduced.
