arm64: dts: fsd: Add Ethernet support for PERIC 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 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.
