The Cubox has an unstable phy address - which can appear at either
address 0 (intended) or 4 (unintended).
SoM revision 1.9 has replaced the ar8035 phy with an adin1300, which
will always appear at address 1.
Change the reg property of the phy node to the magic value 0xffffffff,
which indicates to the generic phy driver that all addresses should be
probed. That allows the same node (which is pinned by phy-handle) to match
either the AR8035 PHY at both possible addresses, as well as the new one
at address 1.
Also add the new adi,phy-output-clock property for enabling the 125MHz
clock used by the fec ethernet controller, as submitted to Linux [1].
Linux solves this problem differently:
For the ar8035 phy it will probe both phy nodes in device-tree in order,
and use the one that succeeds. For the new adin1300 it expects U-Boot to
patch the status field in the DTB before booting
While at it also sync the reset-delay with the upstream Linux dtb.

Sync the device tree with 5.8-rc1.
It basically contains the following extra kernel commit:

ARM: dts: imx6-sr-som: add ethernet PHY configuration
Add ethernet PHY configuration ahead of removing the quirk that
configures the clocking mode for the PHY. The RGMII delay is
already set correctly.

, which passes the 'qca,clk-out-frequency' property and it is important
to specify the correct frequency generated by the AR8035.
