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. Signed-off-by: Tom Rini <trini@konsulko.com>

dtoc: Rename the phandle struct Rather than naming the phandle struct according to the number of cells it uses (e.g. struct phandle_2_cell) name it according to the number of arguments it has (e.g. struct phandle_1_arg).

dtoc: Support properties containing multiple phandle values At present dtoc has a very simplistic view of phandles. It assumes that a property has only a single phandle with a single argument (i.e. two cells per property). This is not true in many cases. Enhance the implementation to scan all phandles in a property and to use the correct number of arguments (which can be 0, 1, 2 or more) when generating the C code. For the struct definitions, use a struct which can hold the maximum number of arguments used by the property.
