drm/panthor: Allow driver compilation

Now that all blocks are available, we can add/update Kconfig/Makefile
files to allow compilation.

v6:
- Add Maxime's and Heiko's acks
- Keep source files alphabetically ordered in the Makefile

v4:
- Add Steve's R-b

v3:
- Add a dep on DRM_GPUVM
- Fix dependencies in Kconfig
- Expand help text to (hopefully) describe which GPUs are to be
  supported by this driver and which are for panfrost.
