ToDo list (incomplete, unordered)
- convert mouse, keyboard, and power to platform devices
- add copyright / driver author / license
- add compile as module support
- move nvec devices to mfd cells?
- adjust to kernel style
- fix clk usage
should not be using clk_get_sys(), but clk_get(&pdev->dev, conn)
where conn is either NULL if the device only has one clock, or
the device specific name if it has multiple clocks.
- move half of the nvec init stuff to i2c-tegra.c
