net: dsa: microchip: Correct initialization order for KSZ88x3 ports

Browse source

Adjust the initialization sequence of KSZ88x3 switches to enable
802.1p priority control on Port 2 before configuring Port 1. This
change ensures the apptrust functionality on Port 1 operates
correctly, as it depends on the priority settings of Port 2. The
prior initialization sequence incorrectly configured Port 1 first,
which could lead to functional discrepancies.
