Changes from v4  --> v5
------------------------
[8/9]            -  Fix compile error reported by kernel test robot

Changes from v3  --> v4
------------------------
The first 2 patches of v3 have been applied.

                 - move t2 from correction to tail tag (again)
                 - ...

Changes from RFC --> v2
------------------------
I think that all open questions regarding the RFC version could be solved.
dts: referenced to dsa.yaml
dts: changed node name to "switch" in example
dts: changed "ports" subnode to "ethernet-ports"
ksz_common: support "ethernet-ports" subnode
tag_ksz: fix usage of correction field (32 bit ns + 16 bit sub-ns)
tag_ksz: use cached PTP header from device's .port_txtstamp function
tag_ksz: refactored ksz9477_tstamp_to_clock()
tag_ksz: pdelay_req: only subtract 2 bit seconds from the correction field
tag_ksz: pdelay_resp: don't move (negative) correction to the egress tail tag
ptp_classify: add ptp_onestep_p2p_move_t2_to_correction helper
ksz9477_ptp: removed E2E support (as suggested by Vladimir)
ksz9477_ptp: removed master/slave sysfs attributes (nacked by Richard)
ksz9477_ptp: refactored ksz9477_ptp_port_txtstamp
ksz9477_ptp: removed "pulse" attribute
kconfig: depend on PTP_1588_CLOCK (instead of "imply")
