aeeb2e6d9c clk: support clk tree dump
The previous code only dump the clk list. This patch is
to support clk tree dump, and also dump the enable_cnt.

The code used in patch is similar to dm_dump_all, but
the code here only filter out the UCLASS_CLK devices.

On i.MX8MM, Partial output:
u-boot=> clk dump
 Rate               Usecnt      Name

80b44fb376 cmd: clk: Handle ENODEV from clk_get_rate
clk_get_rate may return -ENODEV if the clock isn't valid.

Also, make the error cases go through a single path.

ff8eee0330 cmd: clk: Add trivial implementation of clock dump for DM
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.

83d290c56f 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.

ebc675b98d cmd: clk: Check return value from soc_clk_dump
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.

2e192b245e Remove the cmd_ prefix from command files
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.
