Add a "fake" GKI for RISC-V based on the arm64 one. This implementation
simply symlinks the arm64 gki_defconfig and merges in two other configs:
- arch/riscv/configs/64-bit.config
This is an upstream file which enables RISC-V for 64-bit.
- arch/riscv/configs/gki.config
This is a workaround file which enables things the ARM64 architecture
pre-selects, such as GPIOLIB. Without enabling these options, some
drivers are incorrectly dropped from the gki_defconfig.
