## Summary
This PR adds support to USB HUB Multi TT (Transaction Translator).
This is the case for USB2517 USB HUB. Also improved the driver to avoid
mistakes: initially I changed g_id[3], but the in register there is another
field where we need to pass this size again. So it is better to use
ARRAY_SIZE() macro to avoid mistakes.
## Impact
Users will be able to use the USB HUBs Multi-TT like USB2517.
