grlib_irqmp_create(), grlib_gptimer_create() and grlib_apbuart_create() are helpers to create and realize GRLIB devices. Their only caller leon3_generic_hw_init() doesn't check for failure. Only the first can actually fail, and only when the caller fails to set up a pointer property, which is a programming error. Replace qdev_init() by qdev_init_nofail().
