usb: gadget: tegra_udc: use USB charging spec 1.2
Enable the USB charging based on the USB charging spec 1.2. Now we can
detect:
1. SDP (stanardard downstream port)
2. CDP (charging downstream port)
3. DCP (dedicated charging port)
4. None (no cable connected)
5. Non-standard charger
For some non-standard charger, we cannot detect it as DCP device.
If we find a charger detected as USB device but no EP0 packet recieved
with 1s, we then decided this is 1A charger.
