Applying overlay fails silently in case of an error. Add error prints.
Most notably the lack of symbols in the live tree is not reported.

Clean-up all the DT printk functions to use common pr_fmt prefix.
Some print statements such as kmalloc errors were redundant, so just
drop those.

In __of_find_node_by_full_name, add an of_node_get when detecting the
desired element, to ensure that it ends up with a reference count that is
one greater than on entering the function.
Also in __of_find_node_by_full_name, add an of_node_put on breaking
out of the for_each_child_of_node loop, to ensure that the reference
count of the returned value is not double incremented. This change
was made using Coccinelle.
The semantic patch used for this is as follows:
// <smpl>
@@
expression e;
local idexpression n;
@@
for_each_child_of_node(..., n) {
... when != of_node_put(n)
when != e = n
(
return n;
|
+ of_node_put(n);
? return ...;
)
...
}
// </smpl
Finally, add an of_node_put in for_each_child_of_node in the function
__of_adjust_phandle_ref after the value returned by
__of_find_node_by_full_name is no longer useful.

The original resolver format is way too cryptic, switch
to using a tree based format that gets rid of repetitions,
is more compact and readable.
At the same time, update the selftests to using the new local fixups
format.

Introduce support for dynamic device tree resolution.
Using it, it is possible to prepare a device tree that's
been loaded on runtime to be modified and inserted at the kernel
live tree.
