[U-Boot] [PATCH V2 1/2] ARM: tegra: add function to clear pinmux CLAMPING bit

From: Stephen Warren swarren@nvidia.com
This is needed to correctly apply the new Jetson TK1 pinmux config.

Syseng has revamped the Jetson TK1 pinmux spreadsheet, basing the content completely on correct configuration for the board/schematic, rather than the previous version which was based on the bare minimum changes relative to another reference board.
The new spreadsheet sets TRISTATE for any input-only pins. This only works correctly if the global CLAMP bit is not set, so the Jetson TK1 board code has been adjusted accordingly. Apparently syseng have changed their mind since the previous advice that this needed to be set:-/

Syseng has revamped the Jetson TK1 pinmux spreadsheet, basing the content completely on correct configuration for the board/schematic, rather than the previous version which was based on the bare minimum changes relative to another reference board.
The new spreadsheet sets TRISTATE for any input-only pins. This only works correctly if the global CLAMP bit is not set, so the Jetson TK1 board code has been adjusted accordingly. Apparently syseng have changed their mind since the previous advice that this needed to be set:-/

Tom, do these two patches look OK?

I've been side-tracked with other work. Let me take another look, if it's all gravy I'll apply them to u-boot-tegra/next.

This is needed to correctly apply the new Jetson TK1 pinmux config.

v2:
- Use clrbits_le32() rather than open-code read/modify/write statements.
- Update pinmux_set_tristate_input_clamping to match.
