[PATCH 32/32] riscv: Update Kendryte K210 defconfig

[Damien Le Moal]

Update the k210 nommu default configuration nommu_k210_defconfig to
include device drivers for reset, reboot, I2C, gpio, LEDs and SD card
support. The boot options are modified to mount the file system on the
first partition of the SD card as the root file system.
