The dwc3_flush_cache() call was declared and used inconsistently: * The declaration assumed 'int' for addresses (a potential issue when running in a LP64 memory model). * The invocation cast the address to 'long'. This change ensures that both the declaration and usage of this function consistently uses 'uintptr_t' for correct behaviour even when the allocated buffers (to be flushed) reside outside of the lower 32bits of memory.
