mlxsw: spectrum: Support ethtool 'get_ts_info' callback in Spectrum-2

The 'get_ts_info' callback is used for obtaining information about
time stamping and PTP hardware clock capabilities of a network device.

The existing function of Spectrum-1 is used to advertise the PHC
capabilities and the supported RX and TX filters. Implement a similar
function for Spectrum-2, expose that the supported 'rx_filters' are all
PTP event packets, as for these packets the driver fills the time stamp
from the CQE in the SKB.

In the future, mlxsw driver will be extended to support one-step PTP in
Spectrum-2 and newer ASICs. Then additional 'tx_types' will be supported.
