drivers/base/platform.c: don't mark platform_device_register_resndata() as __init_or_module

This reverts 737a3bb9416ce2a7c7a4 ("Driver core: move platform device
creation helpers to .init.text (if MODULE=n)").  That patch assumed that
platform_device_register_resndata() is only ever called from __init code
but that isn't true in the case ioctl->drm_ioctl->radeon_cp_init().
