Subject: [PATCH] ARM: plat-versatile: Make PLAT_VERSATILE_LEDS depend on
 LEDS_CLASS=y

config PLAT_VERSATILE_LEDS needs LEDS_CLASS=y, otherwise I got below build
error when CONFIG_LEDS_CLASS=m.

  LD      init/built-in.o
arch/arm/plat-versatile/built-in.o: In function `versatile_leds_init':
sched-clock.c:(.init.text+0x190): undefined reference to `led_classdev_register'
make: *** [vmlinux] Error 1
