[PATCH v2 0/5] of: generic infrastructure fixes

[Pantelis Antoniou]

The first patch renames the *_node_sysfs methods to _node_post since
this is more accurate when more work takes place besides sysfs
tweaking when the next patch is using a hashtable for phandles.
This is a win for very large blobs with a large number of phandles.
Current we use an exhaustive search which is not optimal at all.

The third patch adds a unittest/benchmark for hashed phandles
along with figures about performance.

A long standing request of applied overlays populating
the symbol list is implemented; this allows staggered overlay
application with a symbol from a previous overlay being used
by another after it.

Finally a pr_fmt for the overlay files is used for
uncluttering the printout a bit.

Changes since v1:
* Reworked phandle hash according to maintainer requests
* Added unittest/benchmark for phandle hash
* Reworked the overlay symbol patch
* Added pr_fmt patch
