msm: kgsl: Fix the graphics bandwidth requests on 8064/8930

Bandwidth requests were created to hit Apps Fabrics nominal and
SVS voltages.  They need to be updated to also hit the right
values for the MM Fabric.  This will allow the default power
level to be at nominal voltage rather than turbo voltage.
