PPC32: Boot wrapper updates. 

The major changes here are:

(1) Combine the pmac and chrp directories into a single
`openfirmware' directory, since both use Open Firmware and the code
was very similar.

(2) Move the Open Firmware interfaces out to a `of1275' directory
and put them in separate files so we only include the ones we need.
This work is due to Leigh Brown.

(3) On PReP and embedded, get the memory size from the memory
controller.  Don't try to ask Open Firmware even on PRePs which
have it.

# (1) For machine targets which produce more than one image, define

# 'znetboot' and 'znetboot.initrd`
# (2) Also, for machine targets which just need to remove the ELF header,

# (3) For machine targets which use the mktree program, define END to be
# the machine name you want in the image, and you can optionally set
# ENTRYPOINT which the image should be loaded at. The optimal setting
# for ENTRYPOINT is the link address.
# (4) It is advisable to pass in the memory size using BI_MEMSIZE and
