leds: lp55xx: Use gpiod_set_value_cansleep()

Use gpiod_set_value_cansleep in the init_device function. Without this
change, the driver may print a warning if the LP55xx enable pin is
connected to a GPIO chip which can sleep (e.g. a GPIO expander):

WARNING: CPU: 0 PID: 2719 at drivers/gpio/gpiolib.c:3051 gpiod_set_value+0x64/0xbc
