20e18e051f tegra2: Add more pinmux functions 
This adds support for changing pinmux functions of pin groups. This is done
by defining a PMUX_FUNC_... enum which can be used to select the function for
each group using pinmux_set_func(). It is also possible to enable
pullup/pulldown, and the existing tristate functionality is retained.

Also provided is a means of configuring a list of pingroups by providing a
configuration table to pinmux_config_table().

c3cf49d247 tegra2: Rename PIN_ to PINGRP_ 
The pin groupings are better named PINGRP, since on Tegra2 they refer to
multiple pins.

Sorry about this, but better to get it right now when there is only a small
amount of code affected.
