ARM: tegra: Create IOMMU map at board_init w/ PLATFORM_IOMMUABLE

Create IOMMU map at board_init with CONFIG_PLATFORM_IOMMUABLE enabled.
ARM: tegra: integration of slave mode support.

Add configurability support for i2s parameters accross all board.

Nvidia need to make theie minds up.
ARM: tegra: thermal: Cleanup thermal dependencies

Cleaned up dependencies related to thermals:

1) Added TEGRA_THERMAL Kconfig option which enables
Tegra Thermal Framework

2) Removed unnecessary ifdefs from board files and thermal
files

Of course this has already been done, just cleaned up for grouper
too now.
ARM: tegra: thermal: Separate skin from thermals

Started seperating skin thermal logic from generic
thermal logic.
ARM: tegra: thermal: Cleaned up thermal framework

Removed shutdown and tc1,tc2,passive delay parameters from
thermal state.
ARM: tegra: thermal: Thermal Refactor

Removed all edp and throttling specific code in the tegra
thermal framework.
ARM: Tegra: Add audio regulators for Grouper

Add regulator id in platform data
Pass this info to ALSA driver using platform data
ARM: tegra: rt5640: remove passing of regulator name

Hardcode the regulator name based on device pin names and
passing correct information through platform data.
arm: tegra: board: remove board specific vbus initializers

Removed the board dependency for the vbus regulators and the vbus gpio in
tegra platforms. Vbus need not be specified from the board files any more.
ARM: tegra: thermal: Refactored thermals

1) Removed skin thermals from tegra_thermal layer
2) Removed throttle initialization from tegra_thermal layer
3) Simplified thermal device interface
4) Create a therm estimator device as a platform device

There were lots of errors here, lets hope this drastically reduces
them.
arm: tegra: add device tree support

Enable device tree support for grouper by adding board compatible tables.

Hopefully this works with the .dts stuff from 3.1.10. If not then
we have even more work on our hands than I thought.
arm: tegra: soc device registration

soc_device_register() for getting soc machine, family,revision
and soc_id.

soc_id format is Revision:SKU:PackageID
