4ff213b8e4 ARM: tegra: clamp inputs on Jetson TK1 
The HW-defined procedure for booting Tegra requires that
CLAMP_INPUTS_WHEN_TRISTATED be enabled before programming the pinmux.
Modify the Jetson TK1 board to do this.

9348532f51 ARM: tegra: make use of GPIO init table on Jetson TK1 
The HW-defined procedure for booting Tegra requires that some pins be
set up as GPIOs immediately at boot in order to avoid glitches on those
pins, when the pinmux is programmed. This patch implements this
procedure for Jetson TK1. For pins which are to be used as GPIOs, the
pinmux mux function need not be programmed, so the pinmux table is also
adjusted.
