mx6sabresd: Simplify the Ethernet PHY configuration
As per the AR8031 datasheet: "For a reliable power on reset, suggest to keep asserting the reset low long enough (10ms) to ensure the clock is stable and clock-to-reset 1ms requirement is satisfied." So do as suggested and also add a 100us delay after deasserting the reset line to guarantee that the PHY ID can be read correctly and the Atheros 8031 PHY driver can be loaded automatically. This results in a simpler code. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
