target/riscv: cpu: Set reset vector based on the configured property value
Now that we have the newly introduced 'resetvec' property in the
RISC-V CPU and HART, instead of hard-coding the reset vector addr
in the CPU's instance_init(), move that to riscv_cpu_realize()
based on the configured property value from the RISC-V machines.
