net: dsa: microchip: add WoL support for KSZ87xx family
Add WoL support for KSZ87xx family of switches. This code was tested
with a KSZ8794 chip.
Implement ksz_common usage of the new device-tree property
'microchip,pme-active-high'.
Make use of the now generalized ksz_common WoL functions, adding an
additional interrupt register write for KSZ87xx. Add helper functions
to convert from PME (port) read/writes to indirect register
read/writes in the dedicated ksz8795 sources. Add initial
configuration during (port) setup as per KSZ9477.
