The device PM subsystem _depends_ on device, not vice-versa. Devices
only hold a reference to struct pm_device now, and initialize this
reference with the value provided in Z_DEVICE_DEFINE. This requirement
can be solved with a forward struct declaration, meaning there is no
need to include device PM headers.

Port some drivers to the recently introduced macros to showcase its
usage and be able to do some initial testing (nRF52840).

The PM callback is no longer referenced as "pm_control" but
"pm_action_cb", so reflect this new naming on the callbacks.

This adds basic support for the Silabs Si7210 hall effect magnetic
position and temperature sensor. It is able to get magnetic field and
temperature in the default scale of the sensor (depending on the
variant). It also supports going into sleep mode without measurements
through the device power management infrastructure.
It is most notably missing support for scale change, measurement
averaging and filtering, and alert pin configuration (threshold,
hysteris, tamper).
