[PATCH v5 4/5] arm64: dts: ti: k3-am62p-ti-ipc-firmware: Split r5f memory region

[Markus Schneider-Pargmann (TI)]

Split the firmware memory region in more specific parts so it is better
described where to find which information. Specifically the LPM metadata
region is important as bootloader software like U-Boot has to know where
that data is to be able to read that data.
