net: dsa: microchip: add periodic output support for the KSZ8463

Browse source

KSZ8463 has several periodic outputs. The way it handles them differ
from the other KSZ switches:
 - KSZ8463 has one set of registers for each of its 12 units while others
   switches share on set of configuration registers for all their units.
 - Maximum size of the KSZ8463 pulse width is smaller
 - KSZ8463 has 12 outputs while others only have 2

Add support for the KSZ8463 periodics outputs through a set of KSZ8463
specific functions.
