Changelog: v3: 1. Remove .map_io() in DT machine descriptor. Since debug_ll_io_init() is called by default. 2. Remove .init_machine() in DT machine descriptor. Since of_platform_populate() is called by default in DT mode. v2: 1. Remove .init_irq() in DT machine descriptor. Since irqchip_init() is called by default in DT mode.
