configs/qemu_riscv{32, 64}_virt: bump OpenSBI to v1.6

This patchs bumps the OpenSBI of qemu_riscv{32,64}_virt to 1.6. The
qemu commands in the readmes are adjusted to use OpenSBI's fw_jump.bin
instead of fw_jump.elf, as the later causes ROM overlapping issues if
OpenSBI 1.6 is used. See:
https://github.com/riscv-software-src/opensbi/issues/372

This commit also updates the opensbi.hash file.
