arm64: dts: qcom: Add PCIe3 and PCIe5 support for HAMOA-IOT-SOM platform
HAMOA IoT SOM requires PCIe3 and PCIe5 connectivity for SATA controller
and SDX65.
Add the required sideband signals (PERST#, WAKE#, CLKREQ#), pinctrl states
and power supply properties in the device tree, which PCIe3 and PCIe5
require.
