Fix the following section mismatch warning - seen when building sparc32:
WARNING: vmlinux.o(.text+0x1ff9c0): Section mismatch in reference from the function kernel_tree_alloc() to the function .init.text:prom_early_alloc()
The function kernel_tree_alloc() references
the function __init prom_early_alloc().
This is often because kernel_tree_alloc lacks a __init
annotation or the annotation of prom_early_alloc is wrong.
prom_early_alloc() is annotated __init, and users of
kernel_tree_alloc() is also annotated __init.
So simply match the annoation of these to fix the warning.

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

Commit e2f2a93b, "of/promtree: add package-to-path support to pdt"
changed dp->name from using the 'name' property to using
package-to-path. This fixed /proc/device-tree creation by eliminating
conflicts between names (the 'name' property provides names like
'battery', whereas package-to-path provides names like
'/foo/bar/battery@0', which we stripped to 'battery@0'). However, it
also breaks of_device_id table matching.
The fix that we _really_ wanted was to keep dp->name based upon
the name property ('battery'), but based dp->full_name upon
package-to-path ('battery@0'). This patch does just that.
This changes all users (except SPARC) of promtree to use the full
result from package-to-path for full_name, rather than stripping the
directory out. In practice, the strings end up being exactly the
same; this change saves time, code, and memory.
SPARC continues to use the existing build_path_component() code.
v2: combine two patches and revert of_pdt_node_name to original version
v3: use dp->phandle instead of passing around node
v4: warn/bail out for non-sparc archs if pkg2path is not set
v5: split of_pdt_build_full_name into sparc & non-sparc versions
v6: Pass NULL to pkg2path before buf gets assigned.
Drop check for pkg2path hook on each and every node.
v7: Don't BUG() when unable to get the full_path; create a
known-unique name instead.

package-to-path is a PROM function which tells us the real (full) name of the
node. This provides a hook for that in the prom ops struct, and makes use
of it in the pdt code when attempting to determine a node's name. If the
hook is available, try using it (falling back to looking at the "name"
property if it fails).

Rather than assuming an architecture defines prom_getchild and friends,
define an ops struct with hooks for the various prom functions that
pdt.c needs. This ops struct is filled in by the
arch-(and sometimes firmware-)specific code, and passed to
of_pdt_build_devicetree.
Update sparc code to define the ops struct as well.

Clean up pdt.c:
- make build dependent upon config OF_PROMTREE
- #ifdef out the sparc-specific stuff
- create pdt-specific header
