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.
