[PATCH v3 2/3] riscv: Introduce CONFIG_RELOCATABLE

This config allows to compile the kernel as PIE and to relocate it at any virtual address at runtime: this paves the way to KASLR and to 4-level page table folding at runtime. Runtime relocation is possible since relocation metadata are embedded into the kernel. Note that relocating at runtime
