nouveau/dispnv50: add cursor pitch check
The hardware needs a FB which is packed. Add checks to make sure
this is the case.
While at it, add debug logs for the existing checks. This allows
user-space to more easily figure out why a configuration is
rejected.
v2:
- Use drm_format_info instead of hardcoding bytes-per-pixel (Ilia)
- Remove unnecessary size check (Ilia)
v3:
- Add missing newlines in debug messages (Lyude)
- Use NV_ATOMIC (Lyude)
- Add missing debug log for invalid format (Ilia)
v4: add plane name in debug messages (Ilia)
