In T30, different pad ctrl group registers have
different pull up and pull down drive strength field
offsets and maximum values. Modified drive_strength
structure to be able to pass the offsets and masks of
each group to ensure that drive strengths are properly
configured.

Adds missing drive pingroups, saves all drive pingroups in
suspend, and restores the pinmux registers in the proper order.

- the reset values for some pin groups in the tegra pin mux can result in
functional errors due to conflicting with actively-configured pin groups
muxing from the same controller. this change adds a known safe, non-
conflicting mux for every pin group, which can be used on platforms
where the pin group is not routed to any peripheral
- also add each pin group's I/O voltage rail, to enable platform code to
map from the pin groups used by each interface to the regulators used
for dynamic voltage control
- add routines to individually configure the tristate, pin mux and pull-
ups for a pingroup_config array, so that it is possible to program
individual values at run-time without modifying other values.
this allows driver power-management code to reprogram individual
interfaces into lower power states during idle / suspend, or to
reprogram the pin mux to support multiple physical busses per
internal controller (e.g., sharing a single I2C or SPI controller
across multiple pin groups)
- move chip-specific data like pingroups and drive-pingroups
out of the common code and into chip-specific code
- fix debug output for group with no pullups
- add a TEGRA_MUX_SAFE function. Setting a pingroup to TEGRA_MUX_SAFE
will automatically select a mux setting that is guaranteed not to
conflict with any of the hardware blocks.
