Add support for the tegra30 based cardhu development board. Cardhu is a tablet
formfactor reference design for tegra30. The patch provides a device tree for
the board, updates Makefile.boot to build the dtb, includes the platform in
Kconfig and updates board-dt.c.

Before we enable the MMU, we must ensure that the TTBR registers contain
sane values. After the MMU has been enabled, we jump to the *virtual*
address of the following function, so we also need to ensure that the
SCTLR write has taken effect.
This patch adds ISB instructions around the SCTLR write to ensure the
visibility of the above.

Convert tegra20 IRQ intialization to the GIC devicetree binding. Modify the
interrupt definitions in the dts files according to
Documentation/devicetree/bindings/arm/gic.txt
v3 (swarren):
* Moved of_irq_init() call into board-dt.c to avoid ifdef'ing it.
- Even with a dummy replacement if !CONFIG_OF, the reference from
tegra_dt_irq_match[] to gic_of_init() would still have to be ifdef'd
- It's plausible that tegra_dt_irq_match[] may need to contain more
entries in the future, and defining what they are seems more suitable
for board-dt.c than irq.c
v2 (swarren):
* Removed some stale GIC init code from board-dt.c
* Undid some accidental 0x -> 0x0 search/replace.

Mark any SDHCI controllers that aren't registered by the board files as
disabled in the device-tree files.
In practice, these controllers:
* Have nothing hooked up to them at all, or
* For ports intended for SDIO usage, the drivers for anything that might
be attached are not in the device-tree yet. If/when drivers appear, the
SD/MMC port can be re-enabled.
The only possible exception is TrimSlice's mico SD slot, but that wasn't
enabled in the board files before anyway, and doesn't work when all the
SDHCI controllers are enabled anyway.

Mark any serial ports that aren't registered by the board files as disabled
in the device-tree files.
In practice, none of the now-disabled ports ended up succeeding device
probing because of the missing clock-frequency property. However,
explicitly marking the devices disabled has the advantage of squashing
the dev_warn() the failed probe causes, and documenting that we intend
the port not to be used, rather than accidentally left out the property.

With board files, all I2C busses run at 400KHz. Fix the device-tree
to be consistent with this. It's possible this is incorrect, but at
least it keeps the board files and device-tree consistent.
Also, disable any I2C controllers that the board files don't register,
also for consistency.

The command-lines present in the existing /chosen node are not necessarily
correct for all users. Ideally, we should simply use the command-line
supplied by the boot-loader.
In fact, using the boot-loader's cmdline is quite easy; either the
bootloader fully supports DT, in which case it can modify the DT passed
to the kernel to include its command-line, or CONFIG_APPENDED_DTB can
be used in conjunction with CONFIG_ARM_ATAG_DTB_COMPAT, and the kernel
will substitute the bootloader's command-line into the DT.

There are no drivers in the kernel at present which can make use of the
memory reserved by /memreserve/, so there is no point reserving it. Remove
/memreserve/ to allow the user more memory. It's also unclear whether any
future driver would actually require /memreserve/, or allocate memory
through some other mechanism.

Create a new device tree source file for Atmel at91sam9g45 SoC family.
The Evaluation Kit at91sam9m10g45ek includes it.
This first basic support will be populated as drivers and boards will be
converted to device tree.
Contains serial, dma and interrupt controllers.
The generic board file still takes advantage of platform data for early serial
init. As we need a storage media and the NAND flash driver is not converted to
DT yet, we keep old initialization for it.
