Hi Jagan,

We kept eMMC as mmc1 for both ROCK 5 Model A and B to keep
compatibility with vendor kernel:
https://github.com/radxa/kernel/blob/stable-5.10-rock5/arch/arm64/boot/dts/rockchip/rk3588-rock-5b.dts#L31

But I am happy to change the alias to mmc0, @Sebastian what do you
think?

Thanks
Chris
