xtensa: drop platform_halt and platform_power_off
Instead of using xtensa-specific platform_halt and platform_power_off callbacks use do_kernel_power_off in the machine_halt and machine_power_off and reimplement existing platform_halt and platform_power_off users with register_sys_off_handler. Drop platform_halt and platform_power_off declarations and default implementations. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
