Suraj Gupta c0732fe787 dmaengine: xilinx_dma: Fix uninitialized addr_width when "xlnx,addrwidth" property is missing 
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.
