SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one.

tegra20: rename tegra2 -> tegra20 This is make naming consistent with the kernel and devicetree and in preparation of pulling out the common tegra20 code.

Tegra: Change Tegra20 to Tegra in common code, prep for T30 Convert TEGRA20_ defines to either TEGRA_ or NV_PA_ where appropriate. Convert tegra20_ source file and function names to tegra_, also. Upcoming Tegra30 port will use common code/defines/names where possible.
