Subject: [PATCH v2 1/3] arm64: dts: ti: k3-am65: Add additional regs for DMA components

From: Manorit Chawdhry <m-chawdhry@...com>

Add additional reg properties for UDMA and RingAcc nodes which are
mostly used by bootloader components before Device Manager firmware
services are available, in order to setup DMA transfers.
