mb/amd/chausie/devicetree: set PSPP policy to DXIO_PSPP_DISABLED
Right now, the PSPP policy that controls if the PCIe lanes can be
dynamically downgraded to a lower speed to save some power needs to be
disabled in order for the link training to be successful. Once this
feature is working, the PSPP policy will be switched to balanced again.
