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).
