arm: tegra: grouper: Switch to external temperature sensor

Disable internal temperature sensor and enable external temperature
sensor.

This may need to be modified further down the line to work fully
for grouper, but for now it might hopefully fix some compilation
errors.
arm: thermal: Removed nonTEGRA_THERMAL_SYSFS logic

All throttling must go through the Linux thermal sysfs
framework now.

Of course this is old so won't work now, but I'm building up the
grouper board files gradually. Therefore this is here for
continuity's sake.
usb: tegra: modify USB platform data structures

Modify USB structures of platform data. Based on the new
platform data structures modifying the initialization in
board files.

Again this should work fine on grouper as everything was the same as
on kai.
