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.
