leds: rt8515: add V4L2_FLASH_LED_CLASS dependency
The leds-rt8515 driver can optionall use the v4l2 flash led class, but it causes a link error when that class is in a loadable module and the rt8515 driver itself is built-in: ld.lld: error: undefined symbol: v4l2_flash_init >>> referenced by leds-rt8515.c >>> leds/flash/leds-rt8515.o:(rt8515_probe) in archive drivers/built-in.a Adding 'depends on V4L2_FLASH_LED_CLASS' in Kconfig would avoid that, but it would make it impossible to use the driver without the v4l2 support. Add the same dependency that the other users of this class have instead, which just prevents the broken configuration.
