Merge tag 'tegra-cleanups' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/tegra into tegra/cleanups 

Minor fixes that weren't urgent enough to go into 3.3. The two paz00
patches are in mainline already but got merged after the branch point
for this branch, so they're duplicated. I also ended up merging in
rmk/for-armsoc into this later on to fix a bug introduced by it, so it's
included but it's not the base of this branch.

* tag 'tegra-cleanups' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/tegra:
  ARM: tegra: Enable CPUIdle on Tegra20
  ARM: tegra: export usb phy symbols
  ARM: tegra: build localtimer support only when needed
  ARM: tegra: select CPU_FREQ_TABLE
  ARM: tegra: select required CPU and L2 errata options
  ARM: tegra: paz00: fix wrong UART port on mini-pcie plug
  ARM: tegra: paz00: fix wrong SD1 power gpio
