arm64: dts: qcom: qcs6490-rb3gen2-industrial-mezzanine: Add second TC9563 PCIe switch node for PCIe1

Browse source

Add a node for the second TC9563 PCIe switch on PCIe1, which is connected
in cascade to the first TC9563 switch via the former's downstream port.

Two embedded Ethernet devices are present on one of the downstream
ports of this second switch as well. All the ports present in the
node represent the downstream ports and embedded endpoints.

The second TC9563 is powered up via the same LDO regulators as the first
one, and these can be controlled via two GPIOs, which are already present
as fixed regulators. This TC9563 can also be configured through I2C.
