arm64: dts: imx95-19x19-evk: Add vpcie3v3aux regulator for PCIe[0,1]
Refer to PCI Express M.2 Specification r5.1 sec3.1.1 Power Sources and
Grounds.
PCI Express M.2 Socket 1 utilizes a 3.3 V power source. The voltage
source, 3.3 V, is expected to be available during the system’s
stand-by/suspend state to support wake event processing on the
communications card.
Add vpcie3v3aux regulator to let this 3.3 V power source always on for
PCIe M.2 Key E connector(PCIe0) on i.MX95 19x19 EVK board.
PCIe1 uses one standard PCIe slot connector, but combines the +3.3v and
+3.3Vaux into a same 3.3v power source, and intends to let it always on.
Add vpcie3v3aux regulator to let this 3.3 V power source always on for
PCIe1 on i.MX95 19x19 EVK board too.
