        irq_domain: Remove 'new' irq_domain in favour of the ppc one

The MMCI driver will not work without two IRQs since this is not
flagged as a single-irq variant. Looking through the complex IRQ
definition for the MMCI on the versatile (including an #if 1
statement forcing MMCI IRQ0 to the VIC) this appears to the the
correct IRQ number for both models.

These were incorrectly introduced and can cause problems for of_irq_init.

The correct way to define a root controller is no interrupt-parent set at
all or the interrupt-parent is set to the root controller itself when
inherited from a parent node.

Wire up support for the XZ decompressor

Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

This patch adds a generic target for SPEAr600 board that can be
configured via the device-tree. Currently the following devices
are supported via the devicetree:

- VIC interrupts
- PL011 UART
- PL061 GPIO
- Synopsys DW I2C
- Synopsys DW ethernet

Other peripheral devices (e.g. SMI flash, FSMC NAND flash etc) will
follow in later patches.

Only the spear600-evb is currently supported. Other SPEAr600
based boards will follow later.

Since the current mainline SPEAr600 code only supports the SPEAr600
evaluation board, with nearly zero peripheral devices (only UART
and GPIO), it makes sense to switch over to DT based configuration
completely now. So this patch also removes all non-DT stuff, mainly
platform device data. The files spear600.c and spear600_evb.c are
removed completely.

This adds all devices that are normally present through the
u8500_init_machine function in the device tree as well, which
will duplicate the devices that are visible.

This will not do much by itself because the device from the
device tree are not matched by any device driver until they
are converted as well. The next step is to move over one
device at a time to actually be used from the device tree
instead of the hardcoded device using auxdata to pass the
correct platform_data.
