tests: Adding more sensor build tests.

Add another group of sensors tests.  Ideally these would be added to
the existing sensor test, however we are at the ROM limit of the
default board, enabling the rest of the bmc150 driver code is
sufficient to break the link.  Ideally these build tests would succeed
on as larger group of boards as possible, therefore rather than switch
the default board to something with more ROM it seems more appropriate
to create more, smaller tests.

Moving the current partial bmc150 build test from its current home to
a new test and adding the missing parts of the driver.

This split of sensor tests into multiple groups is arbitrary,
suggestions for a systematic approach welcome.
