configs/orangepi_r1_defconfig: bump kernel to 5.10.10, u-boot to 2020.10

The probing order of the two mmc controllers (sdcard and sdio wifi) has
changed in kernel 5.10 since commit 21b2cec61c04bd1 (mmc: Set
PROBE_PREFER_ASYNCHRONOUS for drivers that existed in v4.4), so change to
root=PARTUUID=.. instead of hardcoding /dev/mmcblkXp2.
