Add the bus_alloc_resource_anywhere() convenience function.
Summary: Many instances of bus_alloc_resource() simply use 0 and ~0 for start and end to denote 'anywhere' with a given count. To clean this up, introduce a bus_alloc_resource_anywhere() convenience function. Bump __FreeBSD_version for the new API. Reviewed By: jhb Differential Revision: https://reviews.freebsd.org/D5370
