leds: simatic-ipc-leds-gpio: Restore LEDS_CLASS dependency

Browse Source 
A recent rework accidentally lost the dependency on LEDS_CLASS, which
leads to a link error when LED support is disbled:

x86_64-linux-ld: drivers/leds/simple/simatic-ipc-leds.o: in function `simatic_ipc_leds_probe':
simatic-ipc-leds.c:(.text+0x10c): undefined reference to `devm_led_classdev_register_ext'

Add back the dependency that was there originally.
