[PATCH net-next 4/9] mlxsw: spectrum_cnt: Add entry_size_res_id for each subpool and use it to query entry size

[Ido Schimmel <idosch@idosch.org>]

From: Jiri Pirko <jiri@mellanox.com>

Add new field to subpool struct that would indicate which
resource id should be used to query the entry size for
the subpool from the device.
