am3517 don't have the register OMAP343X_CONTROL_PBIAS_LITE and the regulators
like "vmmc", so we don't need set "set_power" function for it.
It would be better to leave omap_hsmmc alone and either:
- define fixed voltage regulators
- or make a noop set_power function
How is the power supplied?
With regard to pbias the change should be:
