platform/x86: fujitsu-laptop: autodetect LCD interface on all models
Presence of ACPI method SBL2 should be checked on all models rather than just the ones with predefined hotkey keycode overrides. Move most of dmi_check_cb_common() to acpi_fujitsu_bl_add(). Adjust indentation to make checkpatch happy.
