dmaengine: at_xdmac: Fix at_xdmac_lld struct definition 



commit 912f7c6f7fac273f40e621447cf17d14b50d6e5b upstream.

The hardware channel next descriptor view structure contains just
fields of 32 bits, while dma_addr_t can be of type u64 or u32
depending on CONFIG_ARCH_DMA_ADDR_T_64BIT. Force u32 to comply with
what the hardware expects.
