iio: accel: kxsd9: Add triggered buffer handling

As is custom with all modern sensors, add a clever burst mode
that will just stream out values from the sensor and provide it
to userspace to do the proper offsetting and scaling.

This is the result when tested with an HRTimer trigger:

Columns shown are x, y, z acceleration, so a positive acceleration
of ~9.81 (shaky due to bad calibration) along the z axis. The
fourth column is the AUX IN which is floating on this system,
it seems to float up to the 2.85V VDD voltage.

To be able to cleanup the triggered buffer, we need to add .remove()

iio: accel: kxsd9: Fix up offset and scaling

This fixes several errors in the offset and scaling of the raw
values from the KXSD9 sensor:

- The code did not convert the big endian value from the sensor
  into the endianness of the host CPU. Fix this with
  be16_to_cpu() on the raw obtained value.

- The code did not regard the fact that only the upper 12 bits of
  the accelerometer values are valid. Shift these
  down four bits to yield the real raw value.

- Further the sensor provides 2048 at zero g. This means that an
  offset of 2048 must be subtracted from the raw value before
  scaling. This was not taken into account by the driver,
  yielding a weird value. Fix this by providing this offset in
  sysfs.

To house the scaling code better, the value reading code was
factored into the raw reading function.

This proper scaling and offseting is necessary to get proper
values out of triggered buffer by offsetting, shifting and scaling
them.

macro, in case the asynchronous channel sends data (to MOST), sporadically
duplicates the synchronous blocks with a size of half the synchronous DBR
buffer.

The patch monitors the size of the unused asynchronous Tx DBR memory
(that includes the ping and pong sizes) to prevent the potential DBR
overflow for the asynchronous Tx DBR buffer.

platform irq (index 1) as the mlb_int of the DIM2 macro.

This patch removes the macro ENABLE_HDM_TEST, which was needed while
doing DIM2-HAL simulations. But these are not conducted anymore.

staging: most: hdm-dim2: fix channel configuration

The DIM2 HDM checks the parameters passed to the function
configure_channel() and adapts the buffer sizes of the configuration
according to the hardware limitation. This patch is needed to init
the HAL layer with the correct values.
