The bmi323 chip is part of handhelds PCs that are run on battery. One of said PC is well-known for its short battery life, even in s2idle: help mitigate that by putting the device in its lowest-consumption state while the peripheral is unused. Have runtime-pm suspend callback save used configuration registers and runtime-pm resume callback restore saved registers to restore the previous state.
