Contribution description

The PR adapts the lis2dh12 driver to work also in I2C mode, which is the used configuration on the thingy52.

The PR is a rebase of #8419 by @haukepetersen and adapts it to changes in the I2C API during the last two years.

Testing procedure

On a board with lis2dh12 over I2C, run tests/driver_lis2dh12 and change DRIVER ?= lis2dh12_spi to DRIVER ?= lis2dh12_i2c in the Makefile.

@MrKevinWeiss tested the original PR with the thingy52. I don't have the thingy52 but a custom samd51 board with the same chip - here the driver is working as expected.

Issues/PRs references

#8419 rebased & updated to the API changes in master (see fixup)

I have a thingy52 but I cannot find my jlink to flash it. Ping me after Oct. 1st and hopefully I can test it (vacation).

Tested with BOARD=thingy52 DRIVER=lis2dh12_i2c make flash term -C tests/driver_lis2dh12/
and got reasonable numbers:

and it makes sense.

Thank you for the test and review!
Had to push a small fixup: for C++, the struct members have to have the same order for initialization and declaration.
