AM57xx evm Rev A3 with SR2.0 platform have incompatible changes for HDMI GPIO requiring new dtb support. This implies we have to properly identify the platform now as well. Hence provide a different board name for the Rev A3 variations. Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
