CONFIG_NEON is no more turning on unconditionally when Armada 375 or
Armada 38x are selected. However we still want it selected for the
reference configuration.

Will the lack of support by the hardware be detected automatically
(Armada 370 does not have neon support for instance)? Or does the
logic relies on the fact that CONFIG_KERNEL_MODE_NEON is disabled?

yes the lack of support by the hardware should be detected automatically,
whereas if CONFIG_NEON is not selected NEON will never be used even if
the hardware is present.
