[PATCH v2 3/3] ARM: dts: imx6: phycore-som: Add phy-reset-duration

[Primoz Fiser]

Without an explicit phy-reset-duration, fec_reset_phy() defaults the
phy-reset-gpios assertion to 1 ms. Extend it to 10 ms for a more robust
PHY reset pulse as otherwise Ethernet PHY probing occasionally fails.

Changes in v2:
- drop patch #3 from v1
- convert patch #4 from v1 to phy-reset-duration instead
