The rp2040 doesn't have a chip ID, but the flash chip connected does. We can get this ID by asking the flash chip directly, but doing so requires disengaging the XIP layer, performing the interrogation of the flash chip, and then re-enabling the XIP layer. This gives us a 64-bit unique ID that we can use as our USB serial number. Signed-off-by: Lasse Dalegaard <dalegaard@gmail.com>
