The Qualcomm PCIe binding deprecates perst-gpios on the host
bridge and expects endpoint reset GPIOs to be described on the root
port as reset-gpios.

Move the PCIe0 and PCIe1 reset and wake GPIOs to their root port
nodes. This keeps the GPIO ownership with the device below the root
port and matches the PCIe binding.

Fix the PCIe reset and wake GPIO description for the Thundercomm
RubikPi3 board.

The board currently describes PERST# and wake GPIOs on the Qualcomm
PCIe host bridge nodes. The Qualcomm PCIe binding deprecates this
and expects endpoint reset GPIOs on the root port nodes as
reset-gpios.

Move the PCIe0 and PCIe1 GPIOs to the corresponding root port
nodes.

Could you please refresh all kodiak DTs at once (and also move PHYs to
the the port node).

Thanks! The requested changes are clear to me now, so I will send a v2
patch directly.
