ARM: tegra: fix GPIO init table programming
Tegra's gpio_config_table() currently uses common GPIO APIs. These used to work without requesting the GPIO, but since commit 2fccd2d96bad "tegra: Convert tegra GPIO driver to use driver model" no longer do so. This prevents any of the GPIO initialization table from being applied to HW. Fix gpio_config_table() to directly program the HW to solve this.
