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 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.

Looks fine at a quick glance, just one nit below, otherwise,

This is my special gift to Thierry to leverage architecture specific memory copying routine which gives another few percent performance boost on image download curtsey Stefan initially experimenting with it on Vybrid (;-p).

Unfortunately enabling this doesn't seem to make much difference on Jetson TK1. TFTP downloads are still around 2 MiB/s. But I suspect that this might be a more general issue with the r8169 driver not being very optimized for speed.

This sounds like, if we enable it, it should be part of one of include/configs/tegra*.h, not just one board-specific file. I think we should drop it from this patch, and add it to an appropriate common file in a separate patch.

OK, will re-submit a v3 with that dropped plus submit a separate patch enabling this across all Tegra boards.
