Kai's USB1 instance is used for modem, so disabling
the hotplug.

I don't know about grouper, but it's worth a try.
ARM: tegra: grouper: Remove tegra_gpio_enable/disable

Removing tegra_gpio_enable and disable calls
from board files as they are supported thorugh
set direction calls in the driver

Move Raydium touch init declaration from board-specific
board-grouper.h to generic board-touch.h
ARM: SoC: Tegra: Convert Tegra to SoC descriptor

Convert all the remaining boards which are not present upstream to SoC

(But for real this time, because grouper is now updated)

I wasn't careful enough in the last commit, so here's some mess
cleaned up hopefully removing future stupid errors.
