Now that leds-gpio is a proper OF platform driver, the Warp can use
the leds-gpio driver rather than the old out-of-kernel driver.
One side-effect is the leds-gpio driver always turns the leds off
while the old driver left them alone. So we have to set them back to
the correct settings.

The P2020 is a dual e500v2 core based SOC with:
* 3 PCIe controllers
* 2 General purpose DMA controllers
* 2 sRIO controllers
* 3 eTSECS
* USB 2.0
* SDHC
* SPI, I2C, DUART
* enhanced localbus
* and optional Security (P2020E) security w/XOR acceleration
The p2020 DS reference board is pretty similar to the existing MPC85xx
DS boards and has a ULI 1575 connected on one of the PCIe controllers.

In these configuration we expect to have large amounts of memory (> 4G)
and thus will bounce via swiotlb some region of PCI address space.
The outbound windows were wasting 512M of address space by leaving a
gap between the top of the outbound window and the 4G boundary. By
moving the top of the outbound window up to the 4G boundary we can
reclaim the vast majority of the 512M (minus space needed for PEXCSRBAR)
and thus reduces the amount of memory we have to bounce.

The powerpc kernel always requires an Open Firmware like device tree
to supply device information. On systems without OF, this comes from
a flattened device tree blob. This blob is usually generated by dtc,
a tool which compiles a text description of the device tree into the
flattened format used by the kernel. Sometimes, the bootwrapper makes
small changes to the pre-compiled device tree blob (e.g. filling in
the size of RAM). To do this it uses the libfdt library.
Because these are only used on powerpc, the code for both these tools
is included under arch/powerpc/boot (these were imported and are
periodically updated from the upstream dtc tree).
However, the microblaze architecture, currently being prepared for
merging to mainline also uses dtc to produce device tree blobs. A few
other archs have also mentioned some interest in using dtc.
Therefore, this patch moves dtc and libfdt from arch/powerpc into
scripts, where it can be used by any architecture.
The vast bulk of this patch is a literal move, the rest is adjusting
the various Makefiles to use dtc and libfdt correctly from their new
locations.

Some U-Boot versions incorrectly set the number of chipselects to two
for Sequoia/Rainier boards while they only have one chipselect hardwired.
This patch adds a workaround for this, hardcoding the number of chipselects
to one for sequioa/rainer board models and reading the actual value from
the memory controller register DDR0_10 otherwise.
It also fixes another error in the way ibm4xx_denali_fixup_memsize
calculates memory size. When testing the DDR_REDUC bit, the polarity is
backwards. A "1" implies 32-bit wide memory while a "0" implies 64-bit
wide memory.

This patch adds pmc nodes to the device tree files so that the boards
will able to use standby capability of MPC837x processors. The MPC837x
PMC controllers are compatible with MPC8349 ones (i.e. no deep sleep).
sleep = <> properties are used to specify SCCR masks as described
in "Specifying Device Power Management Information (sleep property)"
chapter in Documentation/powerpc/booting-without-of.txt.
Since I2C1 and eSDHC controllers share the same clock source, they
are now placed under sleep-nexus nodes.
A processor is able to wakeup the boards on LAN events (Wake-On-Lan),
console events (with no_console_suspend kernel command line), GPIO
events and external IRQs (IRQ1 and IRQ2).
The processor can also wakeup the boards by the fourth general purpose
timer in GTM1 block, but the GTM wakeup support isn't yet implemented
(it's tested to work, but it's unclear how can we use the quite short
GTM timers, and how do we want to expose the GTM to userspace).
