[v3,net-next,0/5] prepare ocelot for external interface control

Message

This patch set is derived from an attempt to include external control
for a VSC751[1234] chip via SPI. That patch set has grown large and is
getting unwieldy for reviewers and the developers... me.

I'm breaking out the changes from that patch set. Some are trivial 
  net: dsa: ocelot: remove unnecessary pci_bar variables
  net: dsa: ocelot: felix: Remove requirement for PCS in felix devices

some are required for SPI
  net: dsa: ocelot: felix: add interface for custom regmaps

and some are just to expose code to be shared
  net: mscc: ocelot: split register definitions to a separate file
  net: mscc: ocelot: expose ocelot wm functions


The entirety of this patch set should have essentially no impact on the
system performance.

v1 -> v2
    * Removed the per-device-per-port quirks for Felix. Might be
    completely unnecessary.
    * Fixed the renaming issue for vec7514_regs. It includes the
    Reported-by kernel test robot by way of git b4... If that isn't the
    right thing to do in this instance, let me know :-)

v2 -> v3
    * Fix an include. Thanks Jakub Kicinski!

Oops - I didn't use git b4 to pull in the reviewed by tags. Sending V4
with those changes and this fix. Apologies!
