The clock is in Hz while the value checked against is in kHz, so
actual frequencies will never be able to be below to max value.
Fix this by specifying the max-value in Hz too.

changes in v2:
- drop the separate vp3-config patch, as vp3 will always get the leftover
  resources, so _should_ be fine (Andy)
- fix error output to also report Hz for the value in Hz (Quentin)
- add received Reviews+Acks
