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.
