revert(bhi160): Re-add hack to fix axis mapping

Originally, commit 1a3dfad3 ("fix(bhi160): Fix interrupt behavior
during initialization") was supposed to fix the BHI160 axis-mapping
issue (see card10/firmware#133) but apparently on some devices it still
needs the original hack to work.  Revert the removal of the axis-mapping
hack from commit 2f56ff36 ("fix(bhi160): Call bhy_mapping_matrix_set
twice for the first time").
