[ Upstream commit c3c38e80016548685e439b23999b4f0bd0ad7e05 ]
This driver can optionally use the v4l2_flash infrastructure, but fails to link built=in if that is in a loadable module:
ld.lld-21: error: undefined symbol: v4l2_flash_release
referenced by leds-tps6131x.c:792 (drivers/leds/flash/leds-tps6131x.c:792)
Add the usual Kconfig dependency for it, still allowing it to be built when CONFIG_V4L2_FLASH_LED_CLASS is disabled.
