If the in-kernel push interface is used we may have a different masks
on the device buffer and the kernel buffer and in this case the device
should generate data for the reunion of the buffers, which is
available at indio_dev->active_scan_mask.
Compiled tested only except for bmc150-accel which was tested at
runtime with the hardware.

After commit b2b49ccbdd (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME may now be changed to depend on
CONFIG_PM.
Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under
drivers/iio/imu/kmx61.c

This fixes parts of kmx61 error handling to make code easier to read and to be
more consistent with IIO coding conventions:
* prefer as single point for error handling instead of duplicating code
for each function
* directly return a value from a case branch instead of breaking
* fix error message for writing REG_CTRL1
Also, add separate error paths for kmx61_trigger_setup/iio_triggered_buffer_setup
calls.

Minimal implementation for KMX61 6-axis accelerometer/magnetometer. It exports
raw accel/magn readings together with scale and sampling frequency.
This driver uses two IIO devices one for accelerometer and one for magnetometer.

The two halves of this part can run largely independently. Hence
a version 4 of this patch followed that reorganized things completely.
