arm64: dts: fsd: Add Ethernet support for FSYS0 Block of FSD SoC
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.
