geni serial needs to express a perforamnce state requirement on CX

Hey,
  I just wanted to follow up on this patch, as I've bisected it
(a5819b548af0) down as having broken qca bluetooth on the Dragonboard
845c.

I haven't yet had time to debug it yet, but wanted to raise the issue
in case anyone else has seen similar trouble.

thanks
