Subject: [PATCH 0/8] adding multiple CPU-Ports

some switch-chips have multiple CPU-Ports

this patch-series adds basic functionality and handle the 2
cpu-Ports of mt7530 on board BananaPi R2

changes to mtk-ethernet-driver are not included yet,
because here are still some issues with watchdog-timeouts

most patches are based on OpenWRT-Patches created by
John Crispin and only ported to DSA-Core 4.15+ with 2 main differences:
  - no change to platform-driver
  - option in dts is named "default_cpu" instead of only "cpu" to
    allow modification from userspace (additional patches needed)

complete source (including eth-patches) is uploaded here:
https://github.com/frank-w/BPI-R2-4.14/commits/4.20-gmac-test

new in v2:
  - added DTS-changes
  - added cover-letter
  - added change of dts-option (default_cpu)

currently posted not to full maintainers-list for first review,
will do it when patches are ready :)
