To the exception of red_led_on in the arm-specific assembly code, all code interacting with the red status LED was guarded by the CONFIG_LED_STATUS_RED symbol, which is enabled in none of the upstream defconfigs. Since the last board which overrode the weak red_led_on function got migrated to the new LED mechanism, there's also no user of the arm-specific assembly code anymore, therefore it can be removed along the other unreachable code sections.
