devicetree: bindings: Extend the bma180 bindings with bma250 info 

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.

For the bma250 the first interrupt listed must be the one

listed must be the one connected to the INT2 pin.
