Hans de Goede ca52a17ba9 ohci-platform: Add support for devicetree instantiation
Add support for ohci-platform instantiation from devicetree, including
optionally getting clks and a phy from devicetree, and enabling / disabling
those on power_on / off.

This should allow using ohci-platform from devicetree in various cases.
Specifically after this commit it can be used for the ohci controller found
on Allwinner sunxi SoCs.

USB OHCI controllers
Required properties:
- compatible : "usb-ohci"
- reg : ohci controller register range (address and length)
- interrupts : ohci controller interrupt
Optional properties:
- clocks : a list of phandle + clock specifier pairs
- phys : phandle + phy specifier pair
- phy-names : "usb"
Example:
ohci0: usb@01c14400 {
compatible = "allwinner,sun4i-a10-ohci", "usb-ohci";
reg = <0x01c14400 0x100>;
interrupts = <64>;
clocks = <&usb_clk 6>, <&ahb_gates 2>;
phys = <&usbphy 1>;
phy-names = "usb";
};
