Add a remoteproc driver for AMD MicroBlaze/V soft-core processor subsystems instantiated in programmable logic and using dual-port BRAM for firmware storage and execution. The driver parses the firmware memory window from the remoteproc device node's reg property, interprets that address and size in the processor-local address space, and then uses standard devicetree address translation through the parent bus ranges property to obtain the corresponding Linux-visible system physical address. The resulting translated region is registered as the executable remoteproc carveout and coredump segment. The processor is controlled through an active-low reset GPIO and a subsystem clock. The clock is enabled before reset is released, and the processor is kept in reset until firmware loading completes. The firmware-name property is optional, allowing firmware to be assigned later through the remoteproc framework. Firmware images without a resource table are also accepted.
