Subject: [PATCH 15/34] leds: apu: remove duplicate DMI lookup data

From: Arnd Bergmann <arnd@...db.de>

Building with W=1 shows a warning about an unused dmi_system_id table:

drivers/leds/leds-apu.c:85:35: error: 'apu_led_dmi_table' defined but not used [-Werror=unused-const-variable=]
   85 | static const struct dmi_system_id apu_led_dmi_table[] __initconst = {

Since the current version doesn't even do anything about the different
implementations but only checks the type of system, just drop the
custom lookup logic and call dmi_check_system() using the table itself.
