Merge branch 'for-3.6/boards' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/boards

From Stephen Warren <swarren@wwwdotorg.org>
This branch contains changes to Tegra board files, and related Kconfig and
Makefile changes. Highlights include:

* Removal of Seaboard/Springbank board files; these boards can now only be
  used with device tree.

* Use of small parts of some non-DT board files from the DT board files. This
  enables all features that the non-DT board files have, when booting from DT.
  This will allow almost complete removal of all non-DT board files in v3.7.

* Other miscellaneous changes.

This branch is based on Tegra's for-3.6/cleanup branch from a previous pull
request.

* 'for-3.6/boards' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra:
  ARM: tegra: use of_default_bus_match_table
  ARM: tegra: add device tree AUXDATA for APBDMA
  ARM: tegra: paz00: enable WiFi rfkill when booting from device tree
  ARM: tegra: harmony: init regulators, PCIe when booting from DT
  ARM: tegra: trimslice: enable PCIe when booting from device tree
  ARM: tegra: remove Seaboard board files
  ARM: tegra: remove CONFIG_MACH_TEGRA_DT
  ARM: tegra: make .dts compilation depend on Tegra2 support
