Add new clk subcommand "clk setfreq", for setting up a clock rate
directly from u-boot cmdline. This is handy for any debugging purposes
towards clocks.

Some clocks are not associated to a DM node, so just parsing the DM is not
enough. This is especially true for root clocks, which typically don't have
any parents. Instead, fetch every registered UCLASS_CLK instance, and dump
these out.

Update depth only when clock uclass is found to have correct display
of command "clk dump".
Without this patch, the displayed depth is the binding depth for
all the uclass and that can be strange as only clock uclass nodes
are displayed.

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

clk_get_rate may return -ENODEV if the clock isn't valid.
Also, make the error cases go through a single path.

Add trivial implementation of the clk dump in case DM is enabled.
This implementation just iterates over all the clock registered
with the CLK uclass and prints their rate.

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.

In case of error in soc_clk_dump function are returned different values
then CMD return values (-1, 0, 1).
For example:
ZynqMP> clk dump
exit not allowed from main input shel
The patch is checking all negative return values and return
CMD_RET_FAILURE which is proper reaction for these cases.

Now that they are in their own directory, we can remove this prefix.
This makes it easier to find a file since the prefix does not get in the
way.
