Hi Coiby,

After removing CONFIG_PM_SLEEP, sprd_pmic_suspend/resume() would not
be built into symbol table with clang compiler though, that would
cause clang compiler report warnings of "unused function" if
CONFIG_PM_SLEEP is not set. So I also prefer to add a __maybe_unused
instead as other people suggested in the mail list.

Thank you for the suggestion! At least Lee prefers to CONFIG_PM_SLEEP
thus to keep the status quo. I'll see he'll change his mind with the
ongoing discussion [1]:)
