Thank you for the point it out. We should add r8a77961 to the soc_rcar_gen3[].
However, I don't know why I could not realize this issue...
So, I investigated this a little and then, IIUC, glob_match() which
soc_device_match() uses seems to return true, if *pat = "r8a7796" and *str =
"r8a77961".

Jens, thank you for your review!

When the max_segs of a mmc host is smaller than 512, the mmc
subsystem tries to use 512 segments if DMA MAP layer can merge
the segments, and then the mmc subsystem exposes such information
to the block layer by using blk_queue_can_use_dma_map_merging().
