[ Upstream commitc0732fe787] When device tree lacks optional "xlnx,addrwidth" property, the addr_width variable remained uninitialized with garbage values, causing incorrect DMA mask configuration and subsequent probe failure. The fix ensures a fallback to the default 32-bit address width when this property is missing.
