Thx, that's better.

Two reasons:
- Our Makefile has ignored the rv32_defconfig file.
- We shouldn't keep the differences that violate the original design principle.
See 'commit 1b937e8faa87 ("RISC-V: Add separate defconfig for 32bit
systems")'

RISC-V: Add separate defconfig for 32bit systems
This patch adds rv32_defconfig for 32bit systems. The only
difference between rv32_defconfig and defconfig is that
rv32_defconfig has CONFIG_ARCH_RV32I=y.
