brcm47xx: add new usb driver for bcma bus and replace ssb usb driver.

This new usb driver uses an extra device so the ehci and the ohci driver are not depending on ech other any more.

+Subject: [PATCH 15/21] bcma: scan for extra address space
+
+Some cores like the USB core have two address spaces. In the USB host
+controller one address space is used for the OHCI and the other for the
+EHCI controller interface. The USB controller is the only core I found
+with two address spaces. This code is based on the AI scan function
+ai_scan() in shared/aiutils.c i the Broadcom SDK.

+
+The old ssb OHCI USB driver will be removed in the next step as this
