[PATCH 5.15 126/139] riscv: fix nommu_k210_sdcard_defconfig

[Greg Kroah-Hartman]

From: Damien Le Moal <damien.lemoal@xxxxxxxxxxxxxxxxxx>

commit 762e52f79c95ea20a7229674ffd13b94d7d8959c upstream.

Instead of an arbitrary delay, use the "rootwait" kernel option to wait
for the mmc root device to be ready.
