I tested again and things were working as expected. This patch adds a
debugfs file for dumping the ring freq table, can you guys test it out
(try disabling the call to update the table, dump it, make sure it's 0,
then re-enable and make sure it's programmed correctly).

The ring frequency scaling table tells the PCU to treat certain GPU
frequencies as if they were a given CPU frequency for purposes of
scaling the ring frequency. Normally the PCU will scale the ring
frequency based on the CPU P-state, but with the table present, it will
also take the GPU frequency
