[PATCH v3] ARM: dts: imx6qdl-pico: Fix Ethernet support

[Fabio Estevam]

Currently, it is no longer possible to retrieve a DHCP address
on the imx6qdl-pico board.

This issue has been exposed by commit f5d9aa79dfdf ("ARM: imx6q:
remove clk-out fixup for the Atheros AR8031 and AR8035 PHYs").

Fix it by describing the qca,clk-out-frequency property as suggested
by the commit above.

Fixes: 98670a0bb0ef14bbb3 ("ARM: dts: imx6qdl: Add imx6qdl-pico support")

Changes since v2:

Now that you have the PHY listed in DT, you could use a phy-handle to
point to it.
