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().

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.

This adds most of the clock functions required by board and driver code:
-query and adjust peripheral clocks
-query and adjust PLLs
-reset and enable control
These functions are plumbed in as required.

Rename CLOCK_PLL_ID to CLOCK_ID which takes account of the fact that the
code now deals with both PLL clocks and source clocks.
This also tidied up the assert() to match the one sent upstream, and fixes
an error in the PWM id.

Seems people fixed their files to use libfoo.o, but didn't actually
update the creation targets to use $(cmd_link_o_target). Update the
rest of the Makefile's found with grep.

These functions provide access to the high resolution microsecond timer
and tidy up a global variable in the code.

In some circumstances, reset_timer_masked() was called be timer_init() in
order to perform architecture specific timer initialisation. In such
cases, the required code in reset_timer_masked() has been moved into
timer_init()
