leds: lgm: fix gpiolib dependency 

Without gpiolib, the driver fails to build:

    drivers/leds/blink/leds-lgm-sso.c:123:19: error: field has incomplete type 'struct gpio_chip'
            struct gpio_chip chip;
                             ^
    include/linux/gpio.h:107:8: note: forward declaration of 'struct gpio_chip'
    struct gpio_chip;
           ^
    drivers/leds/blink/leds-lgm-sso.c:263:3: error: implicit declaration of function 'gpiod_set_value' [-Werror,-Wimplicit-function-declaration]
                    gpiod_set_value(led->gpiod, val);

    static inline void gpio_set_value(unsigned gpio, int value)

    drivers/leds/blink/leds-lgm-sso.c:345:3: error: implicit declaration of function 'gpiod_set_value' [-Werror,-Wimplicit-function-declaration]
                    gpiod_set_value(led->gpiod, 1);
                    ^

Add the dependency in Kconfig.
