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.

U-Boot does not support fancy clock tree structures like the Linux
common clock framework. Implement a simple clock tree model at the
driver level. With this, the clock data will be simplified.

The initial design of the UniPhier clk driver for U-Boot was not
very nice. Here is a re-work to sync it with Linux's clk and reset
drivers, maximizing the code reuse from Linux's clk data.

Move U_BOOT_DRIVER() entry from the data file (clk-uniphier-mio.c)
to the core support file (clk-uniphier-core.c) because I do not want
to repeat the driver boilerplate when I add more clock data.

This does not have much impact on behavior, but makes code look more
more like Linux. The use of devm_ioremap() often helps to delete
.remove callbacks entirely.

This is the initial commit for the UniPhier clock drivers.
Currently, only the Media I/O clock is supported.
