[PATCH v5 3/4] arm64: dts: fsd: Add Ethernet support for FSYS0 Block of FSD SoC

[Swathi K S <swathi.ks@xxxxxxxxxxx>]

The FSD SoC contains two instances of Synopsys DWC QoS Ethernet IP, one
in FSYS0 block and other in PERIC block.
The ethernet interface is managed by a switch which is not managed by
Linux.

Adds device tree node for Ethernet in FSYS0 Block and enables the same for
FSD platform.
