(Commit message updated by Simon Glass <sjg@chromium.org> who is sending
this series originally created by Thierry)

This series adds PCIe support for Tegra20, Tegra30 and Tegra124. The size is
mostly due to the large number of infrastructure that's added (Tegra-
specific drivers required by the PCIe driver). In this version I've included
all patches that were previously split into three separate series. Spreading
them over multiple series is probably not worth it since there might be some
dependencies between them and only the end result gives a completely working
setup.

Patch 1 adds a %pa modifier to printf() to print physical addresses. This is
required to allow code to output such addresses irrespective of whether a 64
bit or 32 bit architecture is built for.

Patch 2 is a minor cleanup to the PCI command that prevents a spew of error
messages if a bus does not exist. Patch 3 modifies the PCI enumeration code
to honor theh restrictions encoded within a host controller driver's
pci_ski_dev() implementation. This is required to prevent exceptions from
the NVIDIA Tegra PCIe controller.

Patch 4 imports the pr_fmt() macro used within the Linux kernel to reduce
the number of characters consumed by literal strings by allowing a source
file to specify a prefix or suffix that should be applied to all format
strings in the file. It is currently used by the debug() and error() macros.

Patch 5 implements a driver for the AS3722 PMIC used on the Venice2 and
Jetson TK1 boards.

Patches 6-11 are preparatory work for the Tegra PCIe controller. They add
missing clock driver functionality as well as drivers for the Tegra powergate
and XUSB pad controller blocks.

Patch 12 adds the PCIe controller driver for Tegra20, Tegra30 and Tegra124.

Device tree nodes and configurations options to enable PCIe on the TrimSlice
(Tegra20), Beaver, Cardhu (Tegra30) and Jetson TK1 (Tegra124) boards are
added in patches 13-21.

Patches 22-25 implement non-cached memory support that will be used in the
last batch of patches to implement more reliable packet transfers in the
r8169 driver. Patch 26 enables non-cached memory support on Tegra.

(Note from Simon: These patches may have already been applied in the ARM
tree, but I can't see them there).

Finally, patches 27-30 implement non-cached memory support and various fixes
in the r8169 driver and add support for the revision of the NIC found on the
Jetson TK1.

The above boards all have an ethernet NIC connected to PCIe, which is what
I tested with.

Note from Simon: I have:

- rebased this on top of the I2C driver model series
- dropped the I2C framework patches
- adjust the PMIC driver and code that calls it to use driver mode
- tested the I2C changes on Jetson-TK1

Changes in v3:
- Use driver model for the PMIC
- Use driver model to access the PMIC
- Use driver model to access the PMIC
- Avoid build error with noncached_init() when the dcache is disabled
- Remove cache-line size warning if dcache is disabled
