Describe APMU controller as a remoteproc device capable of starting the Cortex-R52 cores in Renesas R8A779G0 V4H SoC DT. The APMU IP is in fact a power management unit capable of additional operations, but those are not used by U-Boot so far. Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org>
