dmaengine: apple-admac: Use {low,upp}er_32_bits() to split 64-bit address

2022-06-16T15:41:43Z

If CONFIG_PHYS_ADDR_T_64BIT is not set: drivers/dma/apple-admac.c: In function ‘admac_cyclic_write_one_desc’: drivers/dma/apple-admac.c:213:22: error: right shift count >= width of type [-Werror=shift-count-overflow] 213 | writel_relaxed(addr >> 32, ad->base + REG_DESC_WRITE(channo)); | ^~ Fix this by using the {low,upp}er_32_bits() helper macros to obtain the address parts.
