mfd: axp20x: Add a cell for the usb power_supply part of the axp20x PMICs
Add a cell for the usb power_supply part of the axp20x PMICs.
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.
