command: commands: Add macros to declare commands with subcmds

Most cmd/xxx.c source files expose several commands through a single
entry point. Some of them are doing the sub-command parsing manually in
their do_<cmd>() function, others are declaring a table of sub-commands
and then use find_cmd_tbl() to delegate the request to the sub command
handler.

In either case, the amount of code to do that is not negligible and
repetitive, not to mention that almost no commands are implementing
the auto-completion hook, which means most u-boot commands lack
auto-completion.

Provide several macros to easily define commands exposing sub-commands.

common: command: Rework the 'cmd is repeatable' logic

The repeatable property is currently attached to the main command and
sub-commands have no way to change the repeatable value (the
->repeatable field in sub-command entries is ignored).

Replace the ->repeatable field by an extended ->cmd() hook (called
->cmd_rep()) which takes a new int pointer to store the repeatable cap
of the command being executed.

With this trick, we can let sub-commands decide whether they are
repeatable or not.

We also patch mmc and dtimg who are testing the ->repeatable field
directly (they now use cmd_is_repeatable() instead), and fix the help
entry manually since it doesn't use the U_BOOT_CMD() macro.

common: command: Expose a generic helper to auto-complete sub commands

Some commands have a table of sub-commands. With minor adjustments,
complete_cmdv() is able to provide auto-completion for sub-commands
(it's just about passing the table of commands instead of taking the
global one).
We rename this function into complete_subcmd() and implement
complete_cmdv() as a wrapper around complete_subcmdv().

common: command: Handle USAGE failure separately

command_ret_t enum contains 3 return values but only two are handled
now. Extend cmd_process_error() and handle CMD_RET_USAGE separately.

These commands are affected by this change.
cmd/demo.c
cmd/efi.c
cmd/gpio.c
cmd/qfw.c
cmd/x86/fsp.c
test/dm/cmd_dm.c

And scripts shouldn't be affected because return value is not 0. But
every command implementation can choose what it is correct to pass.
I would expect that RET_USAGE is called when parameters are not
correctly passed (have incorrect value, missing parameters)
and RET_FAILURE when correct parameters are passed but command fails.

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.
