Declaring a static function in a header leads to a warning every
time that header gets included without the function being used:

 static int mv88e6xxx_g2_read(struct mv88e6xxx_chip *chip, int reg, u16 *val)

This marks all such functions in dsa inline to make sure we don't warn
about them.

Fixes: 0d632c3d6fe3 ("net: dsa: mv88e6xxx: add accessors for PTP/TAI registers")
