tablebased pinmux for Tegra20

This series introduces tablebased pinmux to all Tegra20 boards and removes the old way of doing pinmux to avoid any possible conflicts in pin setup.

Patch 1 introduces a temporary CONFIG option for the new pinmux style to avoid breaking bisectability in the middle of the series. This option gets removed again in patch 10.

I have verified that all commits build without errors and tested the new pinmux on my Colibri T20 platform.

For all other boards I took the pinmux configuration from the Linux kernel, but only un-tristated the pads that are used by U-Boot. I can't test the other boards myself, so please everyone with the hardware give this a run and provide a tested-by or a bug report. The series is based denx.de/u-boot-tegra/next.

Patch 11 is more of a RFC and removes the old funcmux as after the switchover nothing uses it anymore. We are not doing real muxing in U-Boot, so there is no need to keep it. But I want to hear from other people if they see any reason to keep this.
