usb: Make host controller types configurable

The host controller type (u/e/xhci) usded by the drivers can be configured
through attributes of the config node. See: README

 ###
 
+Controller configuration
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+The driver can be started using different or all USB controller types a platform
+offers (USB 1.0/2.0/3.0). Note that not all controllers are supported by all
+platforms.  Controllers can be enabled as attribute in the config node of the
+driver.  Supported attributes are: 'uhci', 'ehci', and 'xhci'.
