leds: Fix config reference for AW200xx driver

Commit 36a87f371b7a ("leds: Add AW20xx driver") adds config LEDS_AW200XX
in drivers/leds/Kconfig, but then in drivers/leds/Makefile accidently
refers to CONFIG_LEDS_W200XX; note the missing A!

This typo makes it impossible to add the driver to a kernel build.

Fix this wrong config reference.
