Constraint the mmc framework to only send no more than 65535 blocks in one go during the multi-write command. This constraint comes due to the limitation of 16bit width block counter register at some hardware.

V4: clean patch V3: return to the V1 solution that keep the 65535 constraint, but cut the 512KiB dma limitation V2: add additional members in mmc structure

Applied, thanks.
Thanks Wolfgang!
I'll get to work on a revised multi-block read implementation. A 4x speedup in large MMC reads is worth the effort!
