arm: tegra: initial support for apalis t30

This patch adds board support for the Toradex Apalis T30 a computer on module which can be used on different carrier boards.

For the sake of ease of use we do not distinguish between different carrier boards for now as the base module features are deemed sufficient enough for regular booting.

The following functionality is working so far:
- eMMC boot and environment storage
- Gigabit Ethernet (once Thierry's PCIe as well as Marek's i210 patches hit mainline)
- MMC/SD cards (both 8-bit as well as 4-bit slot)
- USB client/host (dual role port as client e.g. for DFU/UMS, other two ports as host)

---
changes in v4:
- Update device tree to conform to Thierry's latest PCIe specific supply scheme.

changes in v3:
- Drop architecture specific memcpy configuration again in favour of enabling it for all Tegra configurations (via separate patch)
- Fix 8-bit operation of 8-bit MMC/SD card slot

Changes in v2:
- Fixed my odd commenting style within the device tree
- Added gigabit Ethernet (and with it PCIe and PMIC) support
- Fixed PCIe pinmux
- Cleaned-up order of includes in board file
- Added comments in configuration file
- Use architecture specific memcpy to speed up things

This patch got re-based to u-boot-tegra.
