[PATCH] usb: gadget: atmel: Add SAM9X60 support

[Zixun LI]

Add compatible "microchip,sam9x60-udc" and device tree binding.
Compared to SAM9X5 the only difference is the DPRAM memory from the
USB High Speed Device Port (UDPHS) hardware block was increased,
so we can reuse the same endpoint data.

Tested on SAM9X60-Curiosity board with nfs and ums commands.
