drm: deprecate driver date
The driver date serves no useful purpose, because it's hardly ever
updated. The information is misleading at best.
As described in Documentation/gpu/drm-internals.rst:
The driver date, formatted as YYYYMMDD, is meant to identify the date
of the latest modification to the driver. However, as most drivers
fail to update it, its value is mostly useless. The DRM core prints it
to the kernel log at initialization time and passes it to userspace
through the DRM_IOCTL_VERSION ioctl.
Stop printing the driver date at init, and start returning the empty
string "" as driver date through the DRM_IOCTL_VERSION ioctl.
The driver date initialization in drivers and the struct drm_driver date
member can be removed in follow-up.
