Add missing dependency to TAPRIO to avoid build failures such as:
|ERROR: modpost: "taprio_offload_get" [drivers/net/dsa/hirschmann/hellcreek_sw.ko] undefined!
|ERROR: modpost: "taprio_offload_free" [drivers/net/dsa/hirschmann/hellcreek_sw.ko] undefined!

Fix build errors when LEDS_CLASS=m and NET_DSA_HIRSCHMANN_HELLCREEK=y.
This limits the latter to =m when LEDS_CLASS=m.

The switch has internal PTP hardware clocks. Add support for it. There are three
clocks:
* Synchronized
* Syntonized
* Free running
Currently the synchronized clock is exported to user space which is a good
default for the beginning. The free running clock might be exported later
e.g. for implementing 802.1AS-2011/2020 Time Aware Bridges (TAB). The switch
also supports cross time stamping for that purpose.
The implementation adds support setting/getting the time as well as offset and
frequency adjustments. However, the clock only holds a partial timeofday
timestamp. This is why we track the seconds completely in software (see overflow
work and last_ts).
Furthermore, add the PTP multicast addresses into the FDB to forward that
packages only to the CPU port where they are processed by a PTP program.

Add a basic DSA driver for Hirschmann Hellcreek switches. Those switches are
implementing features needed for Time Sensitive Networking (TSN) such as support
for the Time Precision Protocol and various shapers like the Time Aware Shaper.
This driver includes basic support for networking:
* VLAN handling
* FDB handling
* Port statistics
* STP
* Phylink
