Franck Demathieu 4cf64a5f51 staging: nvec: Fix incorrect type of i2c address 
The i2c address is unsigned according to the dt-bindings.
Fix sparse issue (-Wtypesign):

  drivers/staging/nvec/nvec.c:781:35: warning: incorrect type in argument 3 (different signedness)
  drivers/staging/nvec/nvec.c:781:35:    expected unsigned int [usertype] *out_value
  drivers/staging/nvec/nvec.c:781:35:    got int *<noident>

NVEC: An NVidia compliant Embedded Controller Protocol Implementation

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.
