This patchset adds support for optional external vbus supply per port in
ehci-platform.
On some boards, especially when vbus supply requires large current,
and the charge pump on the PHY isn't enough, an external vbus power switch
per port may be used.

Changes in v4:
* Address Roger Quadros comments: split dt-bindings and driver changes.
* Address Robin Murphy comments: simplify vbus_spplies initialization.
Changes in v3:
* Address Felipe Balbi comments: reduce indentation in
ehci_platform_port_power.
* Address Roger Quadros and Alan Stern comments: platforms can have one
external vbus supply per port, so add support to get as many optional
regulator as implemented ports on the host controller.
Changes in v2:
* Address Roger Quadros comments: move regulator_enable/disable from
ehci_platform_power_on/off to ehci_platform_port_power.
