In Linux the bma180 and bmc150-accel driver cover fairly similar chips
from Bosch (just with minor register differences). For the DT schema,
this does not make any difference: They both represent I2C/SPI devices,
have one or two interrupts plus a vdd/vddio-supply.
This means there is no need to duplicate the schema, we can just
document the compatibles for both drivers in a single DT schema.

Some additional notes:
- The datasheet links in bma180 sadly seem all broken for me so
I just dropped them.
- I separated the bma180/bmc150-accel compatibles using a comment.
This is just for clarity, it has no influence on the schema.
- I added myself as second maintainer for the bma255 binding since
Jonathan seemed to be happy to get unlisted for bma180. :)
In the future we could consider combining even more schemas.
In particular bosch,bma400.yaml and bosch,bmi088.yaml are also
almost identical, although they currently specify different interrupt
types. I think in general the situation for those Bosch sensors is
exactly the same: The sensors can be configured to either active-high
or active-low level. However, at the moment neither bma400 or bmi088
actually implement interrupt support. For now I kept those schemas
as-is, I think this is better left up for follow-up patches.
