Before the plethora of platforms gets any worse, establish a common
rule to invoke the wrapper for any platform.  Add arguments to
the rule for initrd, dts, dtb, etc.   Show example usage with initrd.

Create default rules for zImage, and zImage.initrd.  initrd targets
depend on the ramdisk file.

Don't consider targets for zImage.initrd that are targets for zImage.
This means uImage is no longer considered a target for zImage.initrd.

Now that obj-boot is in targets, we can remove (twice) it from clean-files.
zImage.initrd was missing, move zImage nearer where its used, and place
zImage.initrd next to it.  Remove non-ported zImage.sandpoint, and add
auto-generation of unconfigured zImage.initrd* like image-.

This removes the time suspend/restore code that was done through
a PMU notifier in arch/platforms/powermac/time.c.

Instead, introduce arch/powerpc/sysdev/timer.c which creates a sys
device and handles time of day suspend/resume through that.

This should probably be replaced by using the generic RTC framework
but for now it gets rid of the arcane powermac specific hack.
