spi: bcm-qspi: fix suspend/resume #ifdef
The two power management functions are define inside of an #ifdef
but referenced unconditionally, which is obviously broken when
CONFIG_PM_SLEEP is not set:
drivers/spi/spi-bcm-qspi.c:1300:13: error: 'bcm_qspi_suspend' undeclared here (not in a function)
drivers/spi/spi-bcm-qspi.c:1301:13: error: 'bcm_qspi_resume' undeclared here (not in a function)
This replaces the #ifdef with a __maybe_unused annotation that lets
the compiler figure out whether to drop the functions itself,
and uses SIMPLE_DEV_PM_OPS() to refer to the functions.
This will also fill the freeze/thaw/poweroff/restore callback
pointers in addition to suspend/resume, but as far as I can tell,
this is what we want.
