[PATCH v3 2/6] arm64: dts: qcom: qcs6490-rb3gen2: Add node for qps615

Add QPS615 PCIe switch node which has 3 downstream ports and in one
downstream port two embedded ethernet devices are present.

Power to the QPS615 is supplied through two LDO regulators, controlled
by two GPIOs, these are added as fixed regulators. And the QPS615 is
configured through i2c.
