[PATCH] riscv: k210: Reduce DMA block size

[Rick Chen]

> Although the max DMA size supported by the hardware register is 22 bits (or
> 4M), the Linux driver for this device only supports transfers of up to 2M.
> On a device with 8M total memory, I don't think it will make too much of a
> difference.
