To avoid the need of extra boot scripting on AM65x for loading a watchdog firmware, add the required rproc init and loading logic for the first R5F core to the watchdog start handler. In case the R5F cluster is in lock-step mode, also initialize the second core. The firmware itself is embedded into U-Boot binary to ease access to it and ensure it is properly hashed in case of secure boot.
One possible firmware source is https://github.com/siemens/k3-rti-wdt.
The board is responsible for providing the firmware as additional loadable via the U-Boot fit image. The driver will pick up its location from /fit-images/k3-rti-wdt-firmware then.

Applied to u-boot/next, thanks!
