Subject: [PATCH] leds:lp55xx: Correct Kconfig dependency for f/w user helper

The commit [b67893206fc0: leds:lp55xx: fix firmware loading error]
tries to address the firmware file handling with user helper, but it
sets a wrong Kconfig CONFIG_FW_LOADER_USER_HELPER_FALLBACK.  Since the
wrong option was enabled, the system got a regression -- it suffers
from the unexpected long delays for non-present firmware files.

This patch corrects the Kconfig dependency to the right one,
CONFIG_FW_LOADER_USER_HELPER.  This doesn't change the fallback
behavior but only enables UMH when needed.
