The PCIe PHY requires two regulators and are present on the SoM directly, while the PCIe connector also exposes 3V3 and 12V power rails which are available on the baseboard. Considering that 3/4 regulators are always-on on HW level and that the last one depends on a regulator from the PMIC that is specified as always on, this commit should be purely cosmetic and no change in behavior is expected. Let's add all regulators for PCIe on RK3399 Puma Haikou.
