usb:hsotg:samsung: NAK management for EP0 (Setup stage of control transfers)

For SETUP stage of USB control transmission, the NAK shall NOT be
CLEAR.

The SNAK/CNAK control is crucial for this type of driver,
since data arrives to earlier defined requests.

Tested with:
- DFU gadget (various size of the sent data - also packet = MPS)
- Ethernet gadget (CDC and RNDIS)
- Multi Function Gadget (g_multi)

HW:
- Samsung's C210 Universal rev.0
