ARM: tegra: Tegra30 pinmux cleanup
This renames all the pinmux pins, drive groups, and functions so they
have a prefix which matches the type name. These lists are also auto-
generated using scripts that were also used to generate the kernel
pinctrl drivers. This ensures that the lists are consistent between the
two.
The entries in tegra30_pingroups[] are all updated to remove the columns
which are no longer used.
All affected code is updated to match.
This introduces a few changes to pin/group/function naming and the set of
available functions for each pin. The new values now exactly match the
TRM; the chip documentation. I adjusted one entry in
pinmux-config-cardhu.h due to this.
