[PATCH v2 0/4] of: add of_property_alloc/free() and of_node_alloc()

[Clément Léger]

In order to be able to create new nodes and properties dynamically from
drivers, add of_property_alloc/free() and of_node_alloc(). These
functions can be used to create new nodes and properties flagged with
OF_DYNAMIC and to free them.

Some powerpc code was already doing such operations and thus, these
functions have been used to replace the manual creation of nodes and
properties.

---

Changes in V2:
- Remove of_node_free()
- Rework property allocation to allocate both property and value with
  1 allocation
- Rework node allocation to allocate name at the same time the node is
  allocated
- Remove extern from definitions
- Remove of_property_alloc() value_len parameter and add more
  explanation for the arguments
- Add a check in of_property_free to check OF_DYNAMIC flag
- Add a commit which constify the property argument of
  of_property_check_flags()
