riscv: Stop considering R_RISCV_NONE as bad relocations
Even though those relocations should not be present in the final
vmlinux, there are a lot of them. And since those relocations are
considered "bad", they flood the compilation output which may hide some
legitimate bad relocations.

riscv: Check relocations at compile time
Relocating kernel at runtime is done very early in the boot process, so
it is not convenient to check for relocations there and react in case a
relocation was not expected.

There exists a script in scripts/ that extracts the relocations from
vmlinux that is then used at postlink to check the relocations.
