net: dsa: microchip: adapt port offset for KSZ8463's PTP register

Browse Source 
In KSZ8463 register's layout, the offset between port 1 and port 2
registers isn't the same in the generic control register area than in
the PTP register area. The get_port_addr() always uses the same offset
so it doesn't work when it's used to access PTP registers.

Adapt the port offset in get_port_addr() when the accessed register is
in the PTP area.
