Add some features to tegra_defconfig:
* Tegra+MAX98090 audio machine driver, as used on the Venice2 board.
* AMX3722 PMIC, as used on the Venice2 board.
* ChromeOS embedded controller, for the Venice2 keyboard.
Also, rebuild tegra_defconfig on a more recent kernel (3.13-rc1) to
minimize irrelevant diffs showing up when people edit the file.

Let's add the Ethernet so NFSroot works and the first MMC card
so people can patch in more support easily.

As the emac uses the system control module registers for
reset and interrupts, we need to pass those in the platform
data until we have a separate system control module driver.

As we currently need to support a mix of legacy platform data and
device tree intialized data, let's make sure things keep working
for the TWL GPIOs.
Mostly the issue is caused by the fact that DSS does not yet have
device tree bindings, so we need to rely on the TWL GPIO callback
for setting up things like LCD backlight for some boards.
As of_platform_populate() for the TWL GPIO is called by twl-core
after the I2C bus has been initialized, we cannot pass the auxdata
table from the board init code to twl-core like we used to with
just legacy platform data.
So let's use the omap_device bus hook to patch in the platform
data for TWL GPIO until we have sorted out the issues with the
TWL GPIOs and device tree bindings.
The other option was be to initialize twl core using legacy
platform data, which seems like a step backwards as we're moving
to device tree only initialization. And we really don't want to
add custom configuration functions to the TWL GPIO driver either
for this.

Commit 7ce93f3 (ARM: OMAP2+: Fix more missing data for omap3.dtsi file)
fixed missing device tree data for omaps, but did not account for some of the
hardware modules being inaccessible for secure omaps. This causes the
following error on secure omaps:

Let's fix the issue by adding omap34xx-hs.dtsi and omap36xx-hs.dtsi and make
n900, n9 and n950 to use them. This way we have the aes, sham and timer12
disabled for secure devices the same way legacy booting does based on the
omap34xx_gp_hwmod_ocp_ifs and omap36xx_gp_hwmod_ocp_ifs arrays in
omap_hwmod_3xxx_data.c.

The am3517 is wrongly booting as omap3 which means that the am3517
specific devices like Ethernet won't work when booted with device
tree. Now with the new devices defined in am3517.dtsi, let's use
that instead of the omap3.dtsi, and add a separate machine entry
for am3517 so am3517-evm can use it.
