IEEE-1275 spec compliance.
This patch implements the following:
1) Fix bootpath/bootargs handling so that default values are read from NVRAM, and allow multiple space-separated values to be
specified.
2) With correct bootargs handling in place, move the ELF loader over to the new libopenbios unified loaders.
3) Remove all the loader code from all architecture directories sine we don't need it anymore.
4) Simplify the boot word so it invokes platform-specific code where required, then calls load and go as per the specification.
Tested on all my available images for SPARC32, SPARC64 and PPC, and compile-tested on x86.

special-casing directory actions. This is wrong in that in order to list the contents of a directory, open-dev must return true
for any device which contains a valid filesystem, regardless of whether or not the supplied arguments reference a valid path.
This causes us a problem because in order to implement multiple references in boot-device correctly, we have to fail if we open
a specific device with invalid arguments (such as a non-existent file reference). This patch therefore makes the following changes:
1) Create a static method in each of the filesystem packages to implement dir
2) Enhance the partition/disk handlers to record the phandle of any detected filesystem during open
3) Create a new dir method in the partition/disk handlers which invokes the static dir method for the currently detected
filesystem
Hence we can now open a raw device/partition and invoke dir on its filesystem without having to open a specific file-reference
first. Following shortly is a patch to switch the main dir word over to use this new system.

This patch originally started as a fix for PPC, in that the NVRAM initialiser wasn't been run on startup (this is why printenv
on PPC always showed much much less than on SPARC). However, it also showed up some inconsistent logic for boot device
selection, which must also happen *before* boot is called in order for load to work correctly. With this patch applied, bootpath
and bootargs are set from boot-device and boot-args respectively on startup for SPARC32, SPARC64 and PPC.
Note: there is a small chance SPARC32 may break on some images - please let me know if it does.

arguments. With these fixes in place we can now switch the boot word to use (encode-bootpath) which means that the bootpath and
bootarg properties are now set exactly the same when executing boot and/or load.

hierarchy is correct, we can simply pass an ihandle into the loader and it will work correctly regardless of whether it is being
invoked on an entire disk, partition or individual file.
In order to test the new code, start by switching the Fcode loader over to the new infrastructure for testing on SPARC64. Note
this patch also contains a correction to load-base on SPARC which was being set to a value other than 0x4000 which is the
documented default.
