platform/x86: bitland-mifs-wmi: add CONFIG_LEDS_CLASS dependency

The newly added driver requires the LED classdev support
and causes a link failure when that is disabled:

x86_64-linux-ld: vmlinux.o: in function `bitland_mifs_wmi_probe':
bitland-mifs-wmi.c:(.text+0xede02a): undefined reference to `devm_led_classdev_register_ext'
