[PATCH 1/7] arm64: dts: apple: t8122: Keep ps_apcie_phy_sw always-on

[Janne Grunau]

The APCIE_PHY_SW power state is in Apple's device tree a child of the
virtual storage and general purpose PCIe power-states. MacOS however
keeps it always powered on. Mirror this behaviour like the M2 Pro/Max
device trees already do in t602x-pgmr.dtsi.
