board: stm32mp1: fixup the usb product id for USB download gadget
Select the correct USB product id used by the download gadget
for ST stm32mp1 boards.
The board stm32mp1 select the correct product id, as defined in
http://www.linux-usb.org/usb.ids for the STMicroelectronics
vendor id = 0x0483 (CONFIG_USB_GADGET_VENDOR_NUM):
- dfu = 0xdf11 : STM Device in DFU mode
it is the value used by ROM code and reused for stm32prog
command
- fasboot = 0x0afb : Android Fastboot device
- others = 0x5720 (CONFIG_USB_GADGET_PRODUCT_NUM)
Mass Storage Device
it is used for UMS command / usb_dnl_ums
This patch avoid conflict when the same USB VID/PID is used for
ums, fastboot or dfu command (two different protocols associated
to the same PID).
