[PATCH AUTOSEL 5.16 52/52] leds: leds-fsg: Drop FSG3 LED driver

[Sasha Levin <sashal@kernel.org>]

From: Linus Walleij <linus.walleij@linaro.org>

[ Upstream commit b7f1ac9bb6413b739ea91bd61bdf23c9130a8007 ]

The board file using this driver has been deleted and the
FSG3 LEDs can be modeled using a system controller and some
register bit LEDs in the device tree so this driver is no
longer needed.
