[PATCH] Port yaboot logic for various powerpc machine types |

Some powerpc machines require not updating the NVRAM, and some require
adding a CHRP note. This can be handled by existing grub-install
command-line options, but it's friendlier to detect this automatically.
(Some of these machines may not be supported, but I made the list match
for the sake of completeness.)
* grub-core/osdep/basic/platform.c
(grub_install_get_default_powerpc_machtype): New function.
* grub-core/osdep/linux/platform.c
(grub_install_get_default_powerpc_machtype): Likewise.
* grub-core/osdep/windows/platform.c
(grub_install_get_default_powerpc_machtype): Likewise.
* include/grub/util/install.h
(grub_install_get_default_powerpc_machtype): Add prototype.
* util/grub-install.c (main): Set update_nvram to 0 for
pmac_oldworld, chrp_ibm, cell, and generic; set chrp_note to 1 for
chrp_ibm. Pass chrp_note to grub_install_make_image_wrap.
