net/ftgmac100: Add NC-SI mode support
Update the ftgmac100 driver to support NC-SI instead of an mdio phy
where available. This is a common setup for Aspeed AST2x00 platforms.
NC-SI mode is determined from the device-tree if either phy-mode sets it
or the use-ncsi property exists. If set then normal mdio setup is
skipped in favour of the NC-SI phy.
