[PATCH] pinctrl: tegra1x4: initialize at arch_initcall time

[Andrew Bresticker <abrestic@chromium.org>]

Many devices rely on pinctrl/pinmux settings being applied
before probing and some of these may probe before device_initcall
time (e.g. i2c at subsys_initcall).  Move Tegra1x4 pinctrl driver
registration to arch_initcall time so that proper pin settings
can be applied earlier.
