One question in here is whether we want to constrain the number of
interrupts. Some parts definitely only have 1 such pin, and others
2 pins but I can not find information on the bma254.
Oleksandr's email address is bouncing so I've listed myself as
maintainer for this binding until someone else steps up.

The bma180 and related chips should have two regulators attached to
them. The IIO driver currently uses them, document them here as
well.

The bma023, bma150, and smb380 are in the same family as the bma180
and support is being added to the bma180 IIO driver for them.

This adds support for the BMA254 variant of this
accelerometer. The only difference for the simple IIO
driver is that values are 12 bit and the temperature
offset differs by 1 degree.
Whilst wildcards in naming are normally frowned upon:
The cases where I have labeled variables "25x" is where the
models are identical, so as to make things easier for people
that want to add support for BMA253 and BMA255.

'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

The bma180 / bma250 accelerometers share a driver (at least under Linux),
so it makes sense to also have their bindings info in a single .txt.
This commit extends the bma180 bindings with bma250 bindings, specifically
it specifies how the 2 seperate interrupts the bma250 has must be listed
in devicetree. The existing bma180 driver is already fully compatible
with the specified bindings.

This patch adds IIO driver for Bosch BMA180 triaxial
acceleration sensor.
