accel/ivpu: remove driver date from struct drm_driver and all drivers

We stopped using the driver initialized date in commit 7fb8af6
("drm: deprecate driver date") and (eventually) started returning "0"
for drm_version ioctl instead.

Finish the job, and remove the unused date member from struct
drm_driver, its initialization from drivers, along with the common
DRIVER_DATE macros.

v2: Also update drivers/accel (kernel test robot)
