1. ft_create_node was returning the internal pointer rather than a phandle.
2. ft_find_device_rel was treating a "top" phandle of NULL as an error,
rather than as the root of the tree. The old, absolute ft_find_device
is removed, and the relative version is renamed to ft_find_device().

changed the interrupt mapping code so it just uses a static mapping

PIRQA - IRQ9
PIRQB - IRQ10
PIRQC - IRQ11
PIRQD - IRQ12
USB 1.1 OCHI (1c.0) - IRQ12
USB 1.1 OCHI (1c.1) - IRQ9

USB 1.1 ECHI (1c.3) - IRQ11

SATA (1f.1) - IRQ5
SMB (1e.1) - IRQ7
PMU (1e.2) - IRQ7
PATA (1f.0) - IRQ14/15
Took the oppurtunity to refactor the code into a single file so we
don't have to duplicate these fixes on the two current boards in the
tree and several forth coming boards that will also need the code.
Fixed RTC support that requires a dummy memory read on the P2P bridge
to unlock the RTC and setup the default of the RTC alarm registers to
match with a basic x86 style CMOS RTC.
Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure
the PCI IO space has been setup properly before we start poking ISA
registers at random locations.

This patch contains a handful of small fixes to allow the Ebony's
flash to be exposed as MTD devices via the physmap_of driver.
Specifically it:
- Makes a small addition to the device tree and zImage wrapper
to record the correct address for the flash in the device tree based
on the board switches as reported via an FPGA register.
- Prohibits building the old hard-coded "Ebony" flash map on
arch/powerpc kernels, in favour of using physmap_of's device tree
based approach.
- Enables MTD and physmap_of in the Ebony defconfig.

Add support to build the PS3 flash rom image and remove some unneeded
lmb calls.
The PS3's lv1 loader supports loading gzipped binary images from flash
rom to addr zero. The loader enters the image at addr 0x100.
In this implementation a bootwrapper overlay is use to arrange for the
kernel to be loaded to addr zero and to have a suitable bootwrapper
entry at 0x100. To construct the rom image, 0x100 bytes from offset
0x100 in the kernel is copied to the bootwrapper symbol
__system_reset_kernel. The 0x100 bytes at the bootwrapper symbol
__system_reset_overlay is then copied to offset 0x100. At runtime the
bootwrapper program copies the 0x100 bytes at __system_reset_kernel to
addr 0x100.
zImage.ps3 is a wrapped image that contains a flat device tree, an lv1
compatible entry point, and an optional initrd. otheros.bld is the gzip
compresed rom image built from zImage.ps3. otheros.bld is suitable for
programming into the PS3 boot flash memory.
