Prune back Efika fixups to only include changes that are actually required
to get a working system.  Most of the drivers can accept the compatible
properties, even if they don't match the what is recommented in the generic
names recommended practice document.

This patch also adds extra checks so that fixups are not performed blindly.
Instead, the code first verifies that the device tree is faulty before
making any changes.  This way, if the Efika firmware is updated to fix
these issues, then the fixups will no longer get applied.

At this point; here is the list of fixups needed for the efika:
1. If the device_type property on the root node is 'chrp', then Linux won't
   boot.  Change device_type to 'efika' to avoid this condition
2. Add full interrupt list to the bestcomm node.  In actual fact, the
   bestcomm interrupts property is technically correct, it just doesn't
   expose the same granularity as the device driver expects.  All other
   5200 device trees provide a separate irq number for each bestcomm
   channel.  Rather than hack the driver, it's simpler to fix it up
3. /builtin/sound node is missing an interrupts property
4. /builtin/ethernet node is missing a phy-handle property and the
   device driver doesn't know what to do without one.

Update MPC5200 drivers to also look for compatible properties in the
form "fsl,mpc5200-*" to better conform to open firmware generic names
recommended practice as published here:

http://www.openfirmware.org/1275/practice/gnames/gnamv14a.html

This patch should *not* break compatibility with older device trees
which do not use the 'fsl,' prefix.  The drivers will still bind against
the older names also.

The various 5200 dts files don't have values specified for the soc

This reverts commit 5c3f5892,
basically because it changes behaviour even when no fake NUMA
information is specified on the kernel command line.

Firstly, it changes the nid, thus destroying the real NUMA
information.  Secondly, it also changes behaviour in that if a node
ends up with no memory in it because of the memory limit, we used to
set it online and now we don't.

Also, in the non-NUMA case with no fake NUMA information, we do
node_set_online once for each LMB now, whereas previously we only did
it once.  I don't know if that is actually a problem, but it does seem
unnecessary.

This patch extends the Ebony and Walnut platform code to instantiate
the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip
found on both those boards.  The patch uses a helper function to scan
the device tree and instantiate the appropriate platform_device based
on it, so it should be easy to extend for other boards which have mmio
mapped RTC chips.

Along with this, the device tree binding for the ds1743 chips is
tweaked, based on the existing DS1385 OF binding found at:
	http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt
Although that document covers the NVRAM portion of the chip, whereas
here we're interested in the RTC portion, so it's not entirely clear
if that's a good model.

This implements only RTC class driver support - that is /dev/rtc0, not
/dev/rtc, and the low-level get/set time callbacks remain
unimplemented.  That means in order to get at the clock you will
either need a modified version of hwclock which will look at
/dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc.

Now that all platforms using dma_direct_offset setup the
archdata.dma_data correctly, we can change the dma_direct_ops to
retrieve the offset from the dma_data, rather than directly from the
global.

While we're here, change the way the offset is used - instead of
or'ing it into the value, add it.  This should have no effect on
current implementations where the offset is far larger than memory,
however in future we may want to use smaller offsets.

We must always hookup the pci_bus resource 0 to the PHB io_resource
even if the latter is empty (the bus has no IO support).  Otherwise,
some other code will end up hooking it up to something bogus and the
