[PATCH] [2.6.24] Add PPC nvram ioctls to compat_ioctl

Fix the following console warning when running 'nvsetenv', and makes
setting of new variables work again:

ioctl32(nvsetenv:4022): Unknown cmd fd(3) cmd(20007043){t:'p';sz:0}
arg(00000003) on /dev/nvram

That's the IOC_NVRAM_SYNC call.

Please don't. I have this long-term plan of getting rid of fs/compat_ioctl.c,
the better answer is to convert arch/powerpc/kernel/nvram_64.c and
drivers/char/generic_nvram.c from the .ioctl file_operation to
.unlocked_ioctl/.compat_ioctl.
