Switch the driver to use managed resources to simplify error handling.

Instead of creating driver-specific device attributes with
sysfs_create_group() have device core do this by setting up dev_groups
pointer in the driver structure.

The I2C and SPI PM callbacks were identical (though wrapped in some
bouncing out to the bus specific container of the struct device and
then back again to get the drvdata). As such rather than just moving
these to SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() take the opportunity
to unify the struct dev_pm_ops and use the new EXPORT_SIMPLE_DEV_PM_OPS()
macro so that we can drop the unused suspend and resume callbacks as well
as the structure if !CONFIG_PM_SLEEP without needing to mark the callbacks
__maybe_unused.

Up to now adxl34x_remove() returns zero unconditionally. Make it return
void instead which makes it easier to see in the callers that there is
no error to handle.
Also the return value of i2c and spi remove callbacks is ignored anyway.

Suspending and resuming the device should be separate from enabling
and disabling it through sysfs attribute and thus should not alter
ac->disabled flag.
