dfb42fc95d ARM: tegra: pinmux naming consistency fixes
Clean up the naming of pinmux-related objects:
* Refer to drive groups rather than pad groups to match the Linux kernel.
* Ensure all pinmux API types are prefixed with pmux_, values (defines)
  are prefixed with PMUX_, and functions prefixed with pinmux_.
* Modify a few type names to make their content clearer.
* Minimal changes to SoC-specific .h/.c files are made so the code still
  compiles. A separate per-SoC change will be made immediately following,
  in order to keep individual patch size down.

8ca79b2ff4 Tegra30: Cardhu: Add pad config tables/code based on pinmux code
Pad config registers exist in APB_MISC_GP space, and control slew
rate, drive strengh, schmidt, high-speed, and low-power modes for
all of the pingroups in Tegra30. This builds off of the pinmux
way of constructing init tables to configure select pads (SDIOCFG,
for instance) during pinmux_init().

Currently, only SDIO1CFG is changed as per the TRM to work with
the SD-card slot on Cardhu.

Thanks to StephenW for the suggestion/original idea.

f01b631f7d Tegra30: Add/enable Cardhu build (T30 reference board)
This build is stripped down. It boots to the command prompt.
GPIO is the only peripheral supported. Others TBD.

include/configs/tegra-common.h now holds common config options
for Tegra SoCs.
