core: riscv: implement ASLR base address calculation Implement arch_aslr_base_addr() for RISC-V to compute the ASLR base address using the provided seed. The implementation maps addresses across the full virtual address space: - When MSB of new based address is set, the address is mapped to the upper half by extending MSB to 64-bit - Otherwise, it's mapped to the lower half This approach utilizes the entire available virtual address space for ASLR (e.g. 512 GiB for Sv39).
