of: base: of_new_property(): use xstrdup() instead of strdup() ...

At the moment of_new_property() uses xfunctions for memory
allocation so we can use xstrdup() instead of strdup()
for code simplification.

A side effect of this commmit is that
the of_new_property() function can't return NULL
anymore if CONFIG_OFTREE is set.

of: base: Use scoring in DT device matching ...

Port Linux kernel algorithm for both of_device_is_compatible() and
of_match_node(). With this change former now returns a score on the
scale of 0 to INT_MAX/2, and the latter goes through all compatiblity
entries and selects the entry that has the best matching score.

This is needed for SoCs where IP blocks are backwards compatible and
corresponding OF nodes can proclaim compatibility with several entries
found in driver's compatiblity table. One such example would be PIO
pinctrl block on AT91SAM9x5 SoCs which declare compatibility with with
both "atmel,at91sam9x5-pinctrl" and "atmel,at91rm9200-pinctrl".

of: fix of_tree_for_each_node_from() macro ...

of_tree_for_each_node_from() is supposed to iterate over all DT nodes
after the one pointed by the from parameter, but with the current
of_next_node() implementation we cannot access the root node.

Patch of_next_node() to point to root_node when from is NULL.

Doing that also simplifies users of of_tree_for_each_node_from() which
were duplicating the logic to point to the root_node when from is NULL.

string: Fix (v)asprintf prototypes ...

Our asprintf and vasprintf have different prototypes than the glibc
functions. This causes trouble when we want to share barebox code

to use change the existing functions to b(v)asprintf.

of_alias_get assumed that a DT path is always the full node path,
whic is not necessarily the case, as there are other valid path
descriptions. All of them are handled by of_find_node_by_path.

As there is already a preparsed list with all DT aliases that handles
this case properly we can simply reuse that one.
