pine-dontbeevil: update kernel, config, more CMA mem (!336)

* Moved more PinePhone related kernel stuff to the upstream
* Added cma=256M so the CSI subsystem doesn't throw out-of-memory errors
  when capturing at higher than 1280x720 resolutions (but it still hangs)
* Removed a lot of modules that get compiled for DVB tuners after
  enableing the camera stuff.

[ci:skip-build]: doesn't finish in time
