[PATCH] firmware/psci: demote suspend-mode warning to debug level

[Johan Hovold]

On some Qualcomm platform, like SC8280XP, the attempt to set PC mode
during boot fails with PSCI_RET_DENIED and since commit 998fcd001feb
("firmware/psci: Print a warning if PSCI doesn't accept PC mode") this
is now logged at warning level:

	psci: failed to set PC mode: -3

As there is nothing users can do about the firmware behaving this way,
demote the warning to debug level.

Note that a separate change to the cpuidle driver will start logging the
mode actually used:
