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