t23x: overlay: Disable rail-gating for safety IGX

Browse Source 
This change disables GPU rail-gating as it's not a mandatory feature for
safety IGX. The ideal approach for disabling GPU rail-gating should be
deleting the `power-domains` property in GPU node. But the
/delete-property/ is not a valid syntax in the device tree overlay, the
`nvidia,tegra-joint_xpu_rail` is specified to achieve the same as an
alternative.
