Add support for relocations generated by gcc13 for riscv platform
Created by: sepotvin
GCC13 generates some relocations on kernel modules that are not handled by the current kernel loader for riscv. This adds the ones that seems to be missing for the default VisionFive2 configuration. Tested with gcc 13.1.1 (Gentoo 13.1.1_p20230520 p2) and the wlan_ecr6600u_usb module.
