The first AM6x device was the AM654x, but being the first we named it just AM6, since more devices have come out with this same prefix we should switch it to the normal convention of using the full name of the first compatibility device the series. This makes what device we are talking about more clear and matches all the K3 devices added since. Signed-off-by: Andrew Davis <afd@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
