ARM: Tegra: Add to tegra_wm8903_platform_data

Seaboard derivate Kaen has a GPIO to mute the headphone output. Add a field
to tegra_wm8903_platform_data so the board files can pass the GPIO number
for that to the ASoC machine driver.

Also, initialize this new field to a "not present" value for Harmony.
