[PATCH] ARM: Dove: convert usb host controller to DT

[PATCH] ARM: Dove: convert usb host controller to DT

[Sebastian Hesselbarth]

With DT support for orion-ehci also convert Dove to it and
remove the legacy calls and clock aliases.

This patch is based on "ARM: Dove: split legacy and DT setup"
applied to mvebu/boards recently.
