RISC-V: Remove unused code from STRICT_KERNEL_RWX
This patch removes the unused functions set_kernel_text_rw/ro.
Currently, it is not being invoked from anywhere and no other architecture
(except arm) uses this code. Even in ARM, these functions are not invoked
from anywhere currently.
Fixes: d27c3c90817e ("riscv: add STRICT_KERNEL_RWX support")
