net: dsa: microchip: handle KSZ8-specific tc setup in ksz8.c

Browse source

The setup of QDISC_ETS isn't the same for the KSZ8 switches than for
the other switches. It leads to is_ksz8() branches in the common code.

Move the KSZ8-specific portions into ksz8.c by creating two setup_tc()
functions, one dedicated to the KSZ87xx family that only handles the
TC_SETUP_QDISC_CBS case, one for the rest of the KSZ8 that handles both
TC_SETUP_QDISC_CBS and TC_SETUP_QDISC_ETS cases.
It remains some is_kszXXXX() branches because inside the ksz88xx family,
only the ksz88x3 switches support QDISC_ETS.
