arm64: dts: apple: touchbar: Mark ps_dispdfr_be as always-on
The driver depends on boot loader initialized state which resets when the
ps_dispdfr_be power-domain is powered off. This happens on suspend or
when the driver is missing during boot.
Mark the domain as always on until the driver can handle this.
