Subject: [PATCH] chainloader: Define machine types for RISC-V

The commit "Add secureboot support on efi chainloader" didn't add machine
types for RISC-V, so this patch adds them.

Note, that grub-core/loader/riscv/linux.c is skipped because Linux is not
supported yet. This patch might need a new revision once that's the case.
