The smc command can be useful whenever PSCI is used, regardless of
whether barebox provides the secure monitor or not. Have it depend
on ARM_SMCCC instead.

The use of psci_printf here, at least for the phytec-phycore-imx7,
is racy, because access to the UART is not synchronized. This may
lead to characters being swallowed and most certainly to garbled
text. One way around this would be using separate UART ports for
each core or even more generically, just dropping psci_printf and
resorting to inter-core communication over shared-memory to check
whether code execution succeeded.

Fixes a warning that the function is global, but without prototype.
No functional change.

This was supposed to happen in 9efa1f8b ("ARM: psci: wire in smc command
help") along with some other changes. After rebases, the other changes
remained but this one was lost.. Do this right this time and specify the
appropriate BAREBOX_CMD_HELP.

So far, the smc command was only usable when barebox also provides the
secure monitor. It's useful to have it when barebox is a PSCI consumer
as well to test whether the secure monitor works.
Factor out the code into commands/ in preparation to do so.
No functional change.
