Hans de Goede addab6febc iio: accel: bmc150: Add support for DUAL250E ACPI DSM for setting the hinge angle 
Some 360 degree hinges (yoga) style 2-in-1 devices use 2 bmc150 accels
to allow the OS to determine the angle between the display and the base
of the device, so that the OS can determine if the 2-in-1 is in laptop
or in tablet-mode.

On Windows both accelerometers are read (polled) by a special service
and this service calls the DSM (Device Specific Method), which in turn
translates the angles to one of laptop/tablet/tent/stand mode and then
notifies the EC about the new mode and the EC then enables or disables
the builtin keyboard and touchpad based in the mode.

When the 2-in-1 is powered-on or resumed folded in tablet mode the
EC senses this independent of the DSM by using a HALL effect sensor
which senses that the keyboard has been folded away behind the display.

At power-on or resume the EC disables the keyboard based on this and
the only way to get the keyboard to work after this is to call the
DSM to re-enable it.

Call the DSM on probe() and resume() to fix the keyboard not working
when powered-on / resumed in tablet-mode.

This patch was developed and tested on a Lenovo Yoga 300-IBR.
