accel/ivpu: remove DRIVER_DATE conditional drm_driver init

The ivpu struct drm_driver has conditional initialization based on #ifdef
DRIVER_DATE, which is never defined anywhere. Neither are the macros
referenced within the block: DRIVER_DATE, DRIVER_MAJOR, DRIVER_MINOR,
and DRIVER_PATCHLEVEL. With the struct drm_driver date member going away
anyway, just remove the conditional compilation.
