dell-led: remove code related to mic mute LED
With dell_micmute_led_set() moved to drivers/platform/x86/dell-laptop.c, all remnants of the mic mute LED handling code can be removed from drivers/leds/dell-led.c, restoring it back to the state it was in before commit db6d8cc00773 ("dell-led: add mic mute led interface").
