At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

The Tegra CAR (Clock And Reset) module provides control of most clocks
and reset signals within the Tegra SoC. This change implements a driver
for this module. However, since the module implements multiple kinds of
services (clocks, resets, perhaps more), all this driver does is bind
various sub-devices, which in turn provide the real services. This driver
is essentially an "MFD" (Multi-Function Device) in Linux kernel speak.
