IB/core: Create common start/end port functions
commit 0cf18d7723055709faf51b50f5a33253b480637f upstream.
Previously start_port and end_port were defined in 2 places, cache.c and
device.c and this prevented their use in other modules.
Make these common functions, change the name to reflect the rdma
name space, and update existing users.
