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.

dm: Add a new header for block devices At present block devices are tied up with partitions. But not all block devices have partitions within them. They are in fact separate concepts. Create a separate blk.h header file for block devices.

ide: Correct IDE_BUS(dev) macro The IDE_BUS(dev) macro was previously doing dev >> 1. This however is a mis-match of the usage in common/cmd_ide.c and would cause boards with multiple ports / devices to not correctly detect all devices.
