[PATCH v4 1/3] dt-bindings: riscv: describe Svadu as disabled at boot

When both Svade and Svadu are advertised, Svadu is not active at boot and
must be enabled through SBI FWFT before supervisor software can rely on
hardware PTE A/D updates.

Use "disabled" instead of "turned-off" to describe that boot-time state.
This matches the FWFT terminology more closely and avoids the informal
"turned-off" wording without changing the binding semantics.
