mmc: mmci_sdmmc: fix DMA API warning max segment size ...
Turning on CONFIG_DMA_API_DEBUG_SG results in the following warning:
WARNING: CPU: 1 PID: 85 at kernel/dma/debug.c:1302
debug_dma_map_sg+0x2a0/0x3cc mmci-pl18x 58005000.sdmmc: DMA-API: mapping sg
segment longer than device claims to support [len=126976] [max=65536]
dma api debug checks and compares the segment size to dma_get_max_seg_size
(dev->dma_parms->max_segment_size), the sdmmc variant has an internal DMA
and should define its max_segment_size constraint to avoid this warning.
This Patch defines the dev->dma_parms->max_segment_size with the constraint
already set for mmc core (host->mmc->max_seg_size).
