Note that this cell is only for the usb power_supply part and not the ac-power / battery-charger / rtc-backup-bat-charger bits. Depending on the board each of those must be enabled / disabled separately in devicetree as most boards do not use all 4. So in dt each one needs its own child-node of the axp20x node. Another reason for using separate child nodes for each is so that other devicetree nodes can have a power-supply property with a phandle referencing a node representing a single power-supply. The decision to use a separate devicetree node for each is reflected on the kernel side by each getting its own mfd-cell / platform_device and platform-driver. Note this commit also makes some whitespace changes to the intialization of existing cells in axp20x_cells, these are pure whitespace changes, functionally nothing changes.
