This adds device tree support to the nvec driver. By using this method it is no longer necessary to specify platform data through a board file.

NVEC: An NVidia compliant Embedded Controller Protocol Implemenation This is an implementation of the NVEC protocol used to communicate with an embedded controller (EC) via I2C bus. The EC is an I2C master while the host processor is the I2C slave. Requests from the host processor to the EC are started by triggering a gpio line. There is no written documentation of the protocol available to the public, but the source code[1] of the published nvec reference drivers can be a guide. This driver is currently only used by the AC100 project[2], but it is likely, that other Tegra boards (not yet mainlined, if ever) also use it.
