Merge branch 'dsa-port-config'

Andrew Lunn says:

====================
DSA port configuration and status

This patchset allows various switch port settings to be configured and
port status to be sampled. Some of these patches have been posted
before.

The first three patches provide infrastructure for configuring a
switch ports link speed and duplex from a fixed_link phy.

Patch four then uses this infrastructure to allow the CPU and DSA
ports of a switch to be configured using a fixed-link property in the
device tree.

Patches five and six allow a phy-mode property to be specified in the
device tree, and allow this to be used for configuring RGMII delays.

Patches seven through nine allow link status, for example that of an
SFP module, to be read from a gpio.

Changes since v1:

Rewrite 9/9 so that it hopefully does not regression on
