Declaring a static function in a header leads to a warning every
time that header gets included without the function being used:
In file included from drivers/net/dsa/mv88e6xxx/chip.c:42:

This marks all such functions in dsa inline to make sure we don't warn
about them.
Fixes: c6fe0ad2c3 ("net: dsa: mv88e6xxx: add rx/tx timestamping support")
Fixes: 0d632c3d6f ("net: dsa: mv88e6xxx: add accessors for PTP/TAI registers")
