mlxsw: spectrum: Add support for traps specific to Spectrum-1
On Spectrum-1, timestamps for PTP packets are delivered through queues of ingress and egress timestamps. There are two event traps corresponding to activity on each of those queues. This mechanism is absent on Spectrum-2, and therefore the traps should only be registered on Spectrum-1. Carry a chip-specific listener array in mlxsw_sp->listeners and listeners_count. Register listeners from that array in mlxsw_sp_traps_init(). Add a new listener array for Spectrum-1 traps and configure the newly-added mlxsw_sp->listeners with this array. The listener array is empty for now, the events will be added in a later patch.
