mb/amd/chausie/port_descriptors: update DXIO descriptors
Change the DXIO descriptors to match the default PCIe lane mapping on
the chausie board. With this configuration and a board-level rework to
bypass the EC control of the NVMe SSD power supply rail, this
configuration results in the SSD being detected on the root port on bus
0 device 2 function 3 and usable as boot device. This was also validated
against the schematics revision B.
