Some pinmux controls are in a different register set. Add support for
manipulating those in a similar way to existing pins/groups.

Move struct pmux_pingrp_desc type and tegra_soc_pingroups variable
declaration together with other pin/mux level definitions. Now the whole
file is grouped/ordered pin/mux-related then drvgrp-related definitions.
Fix typo in ifdef comment.

Tegra210 has a per-pin option named e_io_hv, which indicates that the
pin's input path should be configured to be 3.3v-tolerant. Add support
for this.
Note that this is very similar to previous chip's rcv_sel option.
However, since the Tegra TRM names this option differently for the
different chips, we support the new name so that the code exactly matches
the naming in the TRM, to avoid confusion.
This patch incorporates a few fixes from Tom Warren <twarren@nvidia.com>.

Tegra210 starts its drive group registers at a different offset from the
APB MISC register block that other SoCs. Update the code to handle this.

T210 support HSM and Schmitt options in the pinmux register (previous
chips placed these options in the drive group register). Update the
code to handle this.

Tegra210 moves some bits around in the pinmux registers. Update the code
to handle this.
This doesn't attempt to address the issues with the group-to-group varying
drive group register layout mentioned earlier. This patch handles the
SoC-to-SoC differences in the mux register layout.

On some future SoCs, some per-drive-group features became per-pin
features. Move all type definitions early in the header so they can
be enabled irrespective of the setting of TEGRA_PMX_SOC_HAS_DRVGRPS.

On some future SoCs, some of the per-drive-group features no longer
exist. Add some ifdefs to support this.

Future SoCs have a slightly different combination of pinmux options per
pin. This will be simpler to handle if we simply have one define per
option, rather than grouping various options together, in combinations
that don't align with future chips.

Tegra's drive group registers have a remarkably inconsistent layout. The
current U-Boot driver doesn't take this into account at all. Add a
comment to describe the issue, so at least anyone debugging the driver
will be aware of this. To solve this, we'd need to add a per-drive-group
data structure describing the layout for the individual register. Since
we don't set up too many drive groups in U-Boot at present, this
hopefully isn't causing too much practical issue. Still, we probably need
to fix this sometime.
Wth Tegra210, the register layout becomes almost entirely consistent, so
this problem partially solves itself over time.
