spmi: pm: drop bus-level PM suspend/resume routines

Browse source 
SPMI defines the behavior of a device in the "SLEEP" state as being
"user-defined or specified by the device manufacturer".  Without
clearly-defined bus-level semantics for low-power states, push the
responsibility of transitioning a device into/out of "SLEEP" into SPMI
device drivers.
