Support UDC on Tegra 20/30/114/124

v2 cover Support UDC on Tegra 20/30/114/124
Some time ago Thierry Reding sent out patches that enabled UDC on NVIDIA Tegra, unfortunately they haven't got enough traction to get into the kernel. I've rebased those patches and added a fix for the Ethernet USB Gadget on Tegra20, Marc Dietrich tested UDC driver on AC100 and Nicolas Chauvet on TK1. Like an original patchset, this series adds support for the peripheral mode only.
Changelog:
V2:
1) Added comments to each of patched USB Ethernet gadget models.
2) Added explanatory comment about why usb_phy_set_suspend() invocation is necessary in tegra_udc_probe().
3) Dropped TrimSlice from patchset because it turned out that it uses USB1 controller for USB-to-SATA.
4) Moved tegra_defconfig patch before DT patches as per Stephen's suggestion.
5) Changed dr_mode to "peripheral" in DT patches since we don't support role mode switching for now.

PATCH v2 1/8 usb: gadget: f_ecm/f_eem/f_rndis: Setup quirk_avoids_skb_reserve
This quirk is required to make USB Ethernet gadget working with HW that can't cope with unaligned DMA. For some reason only f_ncm handles that quirk, let's handle it in the rest of the network models. All models have been tested with a ChipIdea UDC driver on NVIDIA Tegra20 SoC that require DMA to be aligned.

PATCH v2 2/8 usb: chipidea: udc: Support SKB alignment quirk
In reply to a message not in the archiveNVIDIA Tegra20 UDC can't cope with unaligned DMA and require a USB gadget quirk that avoids SKB buffer alignment to be set in order to make Ethernet Gadget working. Later Tegra generations do not require that quirk. Let's add a new platform data flag that allows to enable USB gadget quirk for platforms that require it.

Or you could just have udc_flags in struct tegra_udc_soc_info, so that it would not need to be translated - again saving code, bugs and future developers' time.
