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: rtc: sandbox: Add an emulated I2C RTC device Add a sandbox I2C emulation device which emulates a real-time clock. The clock works off an offset from the current system time, and supports setting and getting the clock, as well as access to byte-width regisers in the RTC. It does not support changing the system time. This device can be used for testing the 'date' command on sandbox, as well as the RTC uclass.

test: dm: rtc: add test of dm_rtc_read, dm_rtc_write Define a few aux registers and check that they can be read/written individually. Also check that one can access the time-keeping registers directly and get the expected results.
