The Marvell Armada RNG uses the same IP as TI from Inside Secure and is already using the binding. The only missing part is the "marvell,armada-8k-rng" compatible string. Rename the binding to inside-secure,safexcel-eip76.yaml to better reflect it is multi-vendor, licensed IP and to follow the naming convention using compatible string.
