drm/docs: Small cleanup in drm-uapi.rst

Browse Source 
- Remove the outdated hunk about driver documentation which somehow
  got misplaced here in the split-up.

- Collect all the testing&validation stuff together and give the CRC
  section a heading for prettier output.

This second part of the GPU Driver Developer's Guide documents driver
code, implementation details and also all the driver-specific userspace
interfaces. Especially since all hardware-acceleration interfaces to
userspace are driver specific for efficiency and other reasons these
interfaces can be rather substantial. Hence every driver has its own
chapter.
