[PATCH] ARM: i.MX93: ele: make A0 firmware optional

[Michael Grzeschik <m.grzeschik@pengutronix.de>]

Since the A0 firmare is not located in the firmware-ele-imx-0.1.0.bin
anymore it is better to make it optional. We add a reference to where
to find the latest version of the firmware in case someone still
uses it.
