The driver supports also BMC156B and BMM150B but these compatibles had
redundant suffix "_magn".  Add existing compatibles marking them
deprecated along with adding a new, proper one for this family of
devices.

Changes since v1:
1. Mark old compatibles as deprecated, add new one.

The compatibles (except BMC150) should not have "_magn" suffix and
BMC156 is compatible with BMM150 so use just one compatible.

Thanks for tidying this up.

The BMC156B is a dual magnetometer and accelerometer chip
so for that one the _magn postfix probably is needed.

Or am I missing something?

The way this does SPI is rather odd but seems to be the same as the bmc150
(two chips with non overlapping register maps).

You're right, only one compatible should be trimmed from suffix. I'll
send v3.

Best regards,
Krzysztof
