Add support for the MPC8323E Reference Development Board (RDB).  The board
is a mini-ITX reference board with 64M DDR2, 16M flash, USB, PCI,
10/100 ethernet, serial, and phone ports.

In two places, ucc_slow_init() passes a physical address instead of the
virtual address to functions that were expecting the latter, causing a kernel
panic.  us_info->regs contains the physical address of the UCC register set.
The registers are ioremap'd to kernel space, and the virtual pointers are
stored in us_regs.  The code was using us_info->regs when it should have been
using us_regs.

Change the Kconfig files so that the Freescale QE options are automatically
selected if a QE device is selected.  Previously, you'd need to manually
select UCC_FAST if you want any "fast" UCC devices, such as Gigabit Ethernet.
Now, the QE Gigabit Ethernet option is always available if the device has a
QE, and UCC_FAST is automatically enabled.  A side-effect is that the
"QE Options" menu no longer exists.

This patch adds a reg.h to the zImage code, with common definitions
for accessing system registers.  For now, this includes functions for
retrieving the PVR and the stack pointer.  This patch then uses the
new reg.h to let start() display the running stack address without
having to explicitly pass the stack as a parameter from the asm code.

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.
