Flashes detected with SFDP should have something like an ID attached to the name #1

Currently flashes detected with SFDP are just named "SFDP". While this is perfectly OK for normal tasks like writing data to the flash, it is a problem for production tests. In the spi_flash test the flasher is used to make sure that the correct flash was equipped. This does not work well if the name is just "SFDP".

The SFDP structure itself does not provide any kind of ID. Maybe we can use a common command like "read JEDEC ID" (0x9f). The routine would need an automatic length detection as the ID is usually repeated with a continuous read.

@trosemann generated a nice ID in the commits 3e1e1a22799be3d2a961ff4b65755b083ff8663a and 972e4b0d5e4d38e837a0f7a5e2dcaac6b50ff7f1. The correct length of the ID is detected. Here is an example for a Spansion S25FL116K flash: "SFDP_014015".
