pvr: remove some stale FIXMEs/pvr_finishmes

* The pvr_finishme() in pvr_CreateImage() was added before vk_image_create() was
  being used and is no longer relevant.

* There's nothing special we need to do for the graphics pipeline flags and
  we don't currently store anything in the pipeline cache, so there's nothing
  to finish here.

* The firmware interface now uses fixed sized structures, so remove related
  FIXME.
