[PATCH v2 3/5] fu540: dtsi: add reset producer and consumer entries

[Sagar Shrikant Kadam]

The resets to DDR and ethernet sub-system are connected to
PRCI device reset control register, these reset signals
are active low and are held low at power-up. Add these reset
producer and consumer details needed by the reset driver.
