Make use of PROC_DEVICETREE to export the tree, and sparc's PROMTREE code to
call into OLPC's Open Firmware to build the tree.
v5: fix buglet with root node check (introduced in v4)
v4: address some minor style issues pointed out by Grant, and explicitly cast
negative phandle checks to s32.
v3: rename olpc_prom to olpc_dt
- rework Kconfig entries
- drop devtree build hook from proc, instead adding a call to x86's
paging_init (similarly to how sparc64 does it)
- switch allocation from using slab to alloc_bootmem. this allows
the DT to be built earlier during boot (during setup_arch); the
downside is that there are some 1200 bootmem reservations that are
done during boot. Not ideal..
- add a helper olpc_ofw_is_installed function to test for the
existence and successful detection of OLPC's OFW.
