Later Tegra generations do not require that quirk. Let's add a new platform data flag that allows to enable USB gadget quirk for platforms that require it.

Make it the same and replace two functions with one to save some lines. This also makes it so that the id cable state is true when the id pin is pulled low, so we change the name of ->state to ->connected to properly reflect that we're interested in the cable being connected.

The main changes are adding several system interfaces for
tuning performance, and each vendors can adjust them according
to their design configurations.

Others are tiny improvements, like more well siTD supports,
USB_DEVICE_A_HNP_SUPPORT supports, etc.
