riscv: do not reimplement generic io functions
RISC-V U-Boot reimplements the generic io functions from asm-generic/io.h. Remove the redundant implementation and include the generic io.h instead. Signed-off-by: Lukas Auer <lukas.auer@aisec.fraunhofer.de> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Rick Chen <rick@andestech.com>
