mb/google/brya: Use USB2_PORT_MAX_TYPE_C for Type-C USB2 port
The patch selects USB2_PORT_MAX_TYPE_C macro for usb2 port#2 in
the device tree of Gimble DVT and Gimble EVT. The macro modifies the
USB2 configuration to indicate the port is mapped to Type-C and sets
Max TX and Pre-emp settings.
The change is required to enable port reset event on the USB2 port#2.
This event is passed to USB3 upstream ports to upgrade back to super
speed (USB3) after a downgrade during low power state. The change is
done for Gimble DVT and EVT boards.
BUG=b:193287279
TEST=Built coreboot for Gimble and tested type A pen drive detect as
super speed device on both the Type-C ports.
