The DRM core uAPI headers are licensed under the MIT license, and carry
copies of the license with slight variations. Replace them with SPDX
headers.

Following a discussion with Daniel Vetter on this topic, add a
clarification in the drm-uapi.rst file that independent closed-source
userspace implementations of software using the DRM uAPI are accepted,
as allowed by the MIT license.
