dmaengine: zx: fix build warning 

commit 067fdeb2f3 upstream.

Fix build warning that related to PAGE_SIZE. The maximum DMA
length has nothing to do with PAGE_SIZE, just use a fix number
for the definition.

drivers/dma/zx_dma.c: In function 'zx_dma_prep_memcpy':
drivers/dma/zx_dma.c:523:8: warning: division by zero [-Wdiv-by-zero]
drivers/dma/zx_dma.c: In function 'zx_dma_prep_slave_sg':
drivers/dma/zx_dma.c:567:11: warning: division by zero [-Wdiv-by-zero]
