Subject: [PATCH net-next v3 2/7] net: dsa: mv88e6xxx: pass directly chip structure to mv88e6xxx_phy_is_internal

Since this function is a simple helper, we do not need to pass a full
dsa_switch structure, we can directly pass the mv88e6xxx_chip structure.
Doing so will allow to share this function with any other function
not manipulating dsa_switch structure but needing info about number of
internal phys
