ARM: tegra: cleanup for 3.13

This branch mainly removes dead code and defines that were useful only
when booting using board files. A few other misc cleanups are also
included.

This branch is based on previous pull request
tegra-for-3.13-deps-for-arm-init-time-cleanup.

* tag 'tegra-for-3.13-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux:
  ARM: tegra: fix ARCH_TEGRA_114_SOC select sort order
  ARM: tegra: make tegra_init_fuse() __init
  ARM: tegra: remove much of iomap.h
  ARM: tegra: move resume vector define to irammap.h
  ARM: tegra: delete gpio-names.h
  ARM: tegra: delete stale header content
  ARM: tegra: remove common.c
