Make OLPC fully depend on device tree, and use it to identify the OLPC
platform details. Some nodes are exposed as platform devices where we
plan to use device tree for device probing.

OLPC_OPENFIRMWARE_DT is just there to be selected by OLPC and selects
OF_PROMTREE. So let OLPC select OF_PROMTREE and remove that extra
config indirection. Fixup code and Makefile and use CONFIG_OF_PROMTREE
instead.

Neither CONFIG_OLPC_OPENFIRMWARE nor CONFIG_OLPC_OPENFIRMWARE_DT are
really necessary.
OLPC selects OLPC_OPENFIRMWARE unconditionally, so move the "select
OF" part under OLPC config option and fixup the dependencies in
Makefiles and code.

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.
