OMAP2xxx clock: GFX functional clock rates are not independently changeable
According to the OMAP242x TRM Rev X Figure 5-15 "Clock Output Control
- Functional Clocks 2", the GFX functional clocks should be marked
both DELAYED_APP and CONFIG_PARTICIPANT, meaning that their rates must
be reprogrammed as part of a larger OPP set change.
