Andres Salomon e2f2a93b63 of/promtree: add package-to-path support to pdt
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).

For symbols still lacking namespace qualifiers, add an of_pdt_ prefix.

Andres Salomon f90c34bd65 of/promtree: no longer call prom_ functions directly; use an ops structure
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.

Andres Salomon 3cfc535c5d of/promtree: make drivers/of/pdt.c no longer sparc-only
Clean up pdt.c:
 - make build dependent upon config OF_PROMTREE
 - #ifdef out the sparc-specific stuff
 - create pdt-specific header

Andres Salomon 9bdf6bab4e sparc: break out some PROM device-tree building code out into drivers/of
Transitioning into making this useful for architectures other than sparc.
This is a verbatim copy of all functions/variables that've been moved.
