This adds a generic driver for platform devices. It works like the PCI
driver and is based on it. This is for devices which do not have an own
bus but their OHCI controller works like a PCI controller. It will be
used for the Broadcom bcma and ssb USB OHCI controller.

Subject: [PATCH 183/186] 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.

This adds a USB driver using the generic platform device driver for the
USB controller found on the Broadcom ssb bus. The ssb bus just
exposes one device which serves the OHCI and the EHCI controller at the
same time. This driver probes for this USB controller and creates and
registers two new platform devices which will be probed by the new
generic platform device driver. This makes it possible to use the EHCI
and the OCHI controller on the ssb bus at the same time.
The old ssb OHCI USB driver will be removed in the next step as this
driver also provide an OHCI driver and an EHCI for the cores supporting
it.
