Subject: [PATCH v3 3/3] arm64: dts: renesas: rzg2l-smarc-som: Add PHY interrupt support for ETH{0/1}

The PHY interrupt (INT_N) pin is connected to IRQ2 and IRQ3 for ETH0
and ETH1 respectively.

Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

v2->v3
* Included irqc-rzg2l.h header

v1->v2
* Used macros of IRQ numbers
