Remove redundant macros since CONFIG_ZTIMER_USEC_TYPE and
CONFIG_ZTIMER_USEC_DEV were already set to their default values.

The motor_driver module has been reworked in a previous commit to be
compliant with RIOT device driver guide.
Thus declaration in board.h is no more needed and should not work
anymore.
Moreover the driver test was calling a callback specific to the native
architecture to simulate the native QDEC periph driver according to
motors speed. This is not relevant as a test should only test the
feature it has been developed for.
