usb: renesas_usbhs: set quirk_avoids_skb_reserve if USB-DMAC is used
This patch sets the quirk_avoids_skb_reserve flag to improve performance
of a network gadget driver (e.g. f_ncm.c) if USB-DMAC is used.
For example (on r8a7795 board + f_ncm.c + iperf udp mode / receiving):
- without this patch: 90.3 Mbits/sec
- with this patch: 273 Mbits/sec
