[PATCH] Allow overlapping resources for platform devices
There are cases in which a device's memory mapped registers overlap with another device's memory mapped registers. On several PowerPC devices this occurs for the MDIO bus, whose registers tended to overlap with one of the ethernet controllers.
By switching from request_resource to insert_resource we can register the MDIO bus as a proper platform device and not hack around how we handle its memory mapped registers.
