[PATCH V2 1/2] ARM: tegra: Add header file for pinctrl constants

[Laxman Dewangan]

This new header file defines pincontrol constants for Tegra to
use from Tegra's DTS file for pincontrol properties option.

Changes from V1:
- Get rid of lots of macro and converge it to TEGRA_PIN_ENABLE/DISABLE.
- Change macro name for PULL UP/DOWN/NONE.
