The regulator power grid changes slightly when using a PM8917 in place of a PM8921 on 8064 targets. Add configuration data so that regulators present only on PM8917 are registered when a PM8917 chip is detected. Also remove PM8921 only regulators when PM8917 is detected. Modify the USB OTG MVS supply chain to handle the replacement of an external 5V boost regulator with the boost present inside of the PM8917. Increase the max_uV value requested in the wlan_riva driver for the iris_vdddig supply to 1225000 in order to handle the case of this supply coming from the S1 regulator in the PM8917 configuration. The S1 regulator only supports 1225000 uV.
