soc/amd/picasso: Remove xhci0_force_gen1 from soc config
To remove the xhci0_force_gen1 and use usb3_port_force_gen1 instead.
The xhci0_force_gen1 is used for force all port on xhci0 to USB3 GEN1.
Now variant can use the usb3_port_force_gen1 to customize which port
it needs to limit.
BUG=b:167651308
BRANCH=zork
TEST=Build, verify the USB3 speed in gen1
