arm: tegra: initial support for apalis tk1Apalis_TK1_LinuxImageV2.6Beta2_20160701

This patch adds support for the Toradex Apalis TK1 acomputer on module
which can be used on different carrier boards.

The module consists of a Tegra TK1 SoC, a PMIC solution, 2 GB of DDR3L
RAM, a bunch of level shifters, an eMMC, a TMP451 temperature sensor
chip, an I210 gigabit Ethernet controller and a SGTL5000 audio codec.
Furthermore, there is a Kinetis MK20DN512 companion micro controller for
analogue, CAN and resistive touch functionality which is not yet
supported.

This is known to boot into either a basic Angstrom/OpenEmbedded/Yocto
or L4T/JetPack Ubuntu based image.

The following things are known to work to a certain extend:
- analogue/digital audio
- debug UART1
- DVFS power management incl. low power core migration
- eMMC
- gigabit Ethernet
- GPIOs
- HDMI (incl. HDA audio)
- I2C
- LVDS
- PCIe
- SATA
- SD/MMC cards
- temperature sensor
- USB host ports

The rest is untested.
