target/riscv: Allocate itrigger timers only once
riscv_trigger_init() had been called on reset events that can happen several times for a CPU and it allocated timers for itrigger. If old timers were present, they were simply overwritten by the new timers, resulting in a memory leak. Divide riscv_trigger_init() into two functions, namely riscv_trigger_realize() and riscv_trigger_reset() and call them in appropriate timing. The timer allocation will happen only once for a CPU in riscv_trigger_realize().
