Julian Andres Klode ff169c1487 staging: nvec: Enable the capslock LED in the keyboard driver 
When the caps lock key is pressed, toggle the associated
LED. According to Nvidia code, we should send 0x01 where
we sent 0x07, but this does not appear to work correctly
on the AC100.

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.
