[PATCH v5 4/4] arm64: dts: fsd: Add Ethernet support for PERIC 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 connected to a switch which is not managed by
Linux.

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