66de3eee79 tegra: tegra124: Add a PMC syscon driver
The PMC can be modelled as a syscon peripheral. Add a driver for this
so that it can be accessed by drivers when needed. Enable it for tegra124
boards.

1680d7b6de ARM: tegra: create common XUSB padctl driver file
A fair amount of the XUSB padctl driver will be common between Tegra124
and Tegra210. To avoid cut/paste between the two chips, create a new
file that will contain the common code, and convert the Tegra124 code to
use it. This change doesn't move every last piece of code that can/will be
shared, but rather concentrates on moving code that can be moved with zero
changes, so there are no other diffs mixed in.

ffdf9f9ae0 tegra124: Add PSCI support for Tegra124
This is based on Thierry Reding's work and uses Ian Campell's
preparatory patches. It comes with full support for CPU_ON/OFF PSCI
services. The algorithm used in this version for turning CPUs on and
off was proposed by Peter De Schrijver and Thierry Reding in
http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/210881. It
consists of first enabling CPU1..3 via the PMC, just to powergate them
again with the help of the Flow Controller. Once the Flow Controller is
in place, we can leave the PMC alone while processing CPU_ON and CPU_OFF
PSCI requests.
