Allen Martin 1ed0b51b7d tegra: add CONSOLE_MUX support to tegra-kbc
Add support for CONSOLE_MUX to tegra-kbc driver.  This requires
adding a flag to struct keyb to know the driver has already been
initialized so if we try to initialize it again we can just return
success.  Also call into iomux_doenv() from drv_keyboard_init to
re-evaluate the stdin string.
