panfrost: Update SET_VALUE with information from igt

It's not a tiler specific initialization; it's a generic GPU-side write
primitive that may be used for tiler reset on midgard.

  * Within a batch (panfrost_job), there are various types of Mali jobs:
  *
- *  - SET_VALUE: initializes tiler
+ *  - SET_VALUE: generic write primitive, used to zero tiler field
  *  - VERTEX: runs a vertex shader
  *  - TILER: runs tiling and sets up a fragment shader
  *  - FRAGMENT: runs fragment shaders and writes out
