board: toradex: make USB PID from config block optional

Browse source 
If config block support is enabled, USB gadget modes unconditionally
use Toradex Product ID as USB PID. Some applications might prefer a
different and/or static USB PID. Add a Kconfig configuration option
to descide whether to use USB PID from config block or the fallback
config option CONFIG_G_DNL_PRODUCT_NUM.

help
Use the Toradex product ID learned from the config block as USB
product ID. An offset of 0x4000 is added to the product ID since
inside the Toradex vendor ID (0x1b67) the range starting from
offset 0x4000 is reserved for Colibri/Apalis modules.
