dt: add of_alias_scan and of_alias_get_id
The patch adds function of_alias_scan to populate a global lookup table with the properties of 'aliases' node and function of_alias_get_id for drivers to find alias id from the lookup table. v3: Split out automatic addition of aliases on id lookup so that it can be debated separately from the core functionality. v2: - Add of_chosen/of_aliases populating and of_alias_scan() invocation for OF_PROMTREE. - Add locking - rework parse loop Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Acked-by: David S.
