IB/core: Add per port immutable struct to ib_device
As of commit 5eb620c81ce3 "IB/core: Add helpers for uncached GID and P_Key
searches"; pkey_tbl_len and gid_tbl_len are immutable data which are stored in
the ib_device.
The per port core capability flags to be added later are also immutable data to
be stored in the ib_device object.
In preparation for this create a structure for per port immutable data and
place the pkey and gid table lengths within this structure.
"get_port_immutable" is added as a mandatory device function to allow the
drivers to fill in this data.
