target/riscv: calloc() memory per register.

This replaces a static array with 8 bytes per register. When there are
vector registers larger than 8 bytes, they would end up clobbering each
other's values. I can't believe I didn't catch this earlier.

See https://github.com/riscv/riscv-openocd/pull/658
