This change modifies the Tegra board files to be named the same way for consistency. Once a related change is made in U-Boot, this will cause both U-Boot and the kernel to use the same names for the .dts files and SoC identifiers, thus allowing U-Boot's recently added "soc" and "board" environment variables to be used to construct the name of Tegra .dtb files, and hence allow board-generic U-Boot bootcmd scripts to be written.

Work on this is in progress, but not yet complete. Manually initialize PCIe when booting from device tree, in order to bring DT support to the same feature level as board files, which will in turn allow board files to be deprecated. PCIe hosts the wired Ethernet controller on TrimSlice. To support this, add infra-structure to board-dt-tegra20.c for board- specific initialization code. Once device tree support for the relevant features is in place, this code will be removed.

This change adds support for the following specific configuration: E1120 motherboard E1108 CPU board E1116 PMU board The motherboard configuration switches are set as follows: SW1=0 SW2=0 SW3=5 S1/S2/S3/S4 all on, except S3 7/8 are off. Other combinations of daugher boards may work to varying degrees, but will likely require some SW adjustment.

Patch 2 got applied to the regulator tree as 7c7fac3 "regulator: tps6586x: add support for input supply" without this patch. This broke regulator support on Harmony.

However, it appears that I only tested it when booting using board files, not when booting using device tree. This change fixes two problems with regulators when booting using device tree: 1) That patch only created the vdd_sys regulator when booting using a board file. Since this is the root of the whole regulator tree, this caused no regulators to successfully initialize when booting using device tree. The registration of vdd_sys is moved to fix this. 2) When booting use DT, the regulator core sets has_full_constraints, which in turn causes the core to turn off any regulators not marked as always on. Some of the affected regulators are required for basic system operation. To solve this, add always on constraints to all relevant regulators. This doesn't affect booting using a board file since nothing sets has_full_constraints in that case.
