The existing routines hard-coded the initial values into the device tree at startup, and then didn't update them which could
allow the romvec memory lists and the device tree memory properties to become out of sync.

The existing code appeared to be allocating memory from the wrong property (map rather than avail) and so rather than allocating
memory starting from just below the OpenBIOS image downwards, it was simply reducing the reported size of the OpenBIOS image.

This appears to resolve issues with OpenBIOS crashing when calling OBP functions through the romvec interface due to
stack/register issues. Note that this patch also implements pv_printf() and pv_putstr() which appears to fix issues with
displaying error messages during Solaris 8 boot.

The extra stack arguments are actually placed within %o1-%o5 but unfortunately there doesn't seem to be a way of passing the
number of parameters using the romvec API. Hence we go through the argument list and start pushing arguments onto the Forth
stack from the first non-zero argument before executing the Forth string.

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.

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.

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.
