mb/amd/chausie/devicetree: add PCIe clock output configuration
The general purpose PCIe clock outputs 0, 1 and 3 are used with their
corresponding clock request pins, so set the gpp_clk_config to
GPP_CLK_REQ for those and disable the unused output 2. This matches the
DXIO descriptor in port_descriptors.c.
