Realtek DHC RTD SoCs integrate dwc3 IP and has some customizations to support different generations of SoCs. The RTD1619b subclass SoC only supports USB 2.0 from dwc3. The driver can set a maximum speed to support this. Add role switching function, that can switch USB roles through other drivers, or switch USB roles through user space through set /sys/class/usb_role/.

Platform-specific glue layers go here
NOTICE: Make sure your glue layer doesn't depend on anything
which is arch-specific and that it compiles on all situations.
We want to keep this requirement in order to be able to compile
the entire driver (with all its glue layers) on several architectures
and make sure it compiles fine. This will also help with allmodconfig
and allyesconfig builds.
