Add a SPI command class to `struct flashchip`
By default, we want to probe for SPI25 chips only. Other SPI use cases,
like the ENE/EDI protocol, might use commands that can confuse these
common chips.
Now, flashrom will probe for a chip only if one of these conditions is
true:
1) no chip has been specified AND the chip uses the SPI25 commands
2) this chip has been specified by -c | --chip <chipname>
The CLI can later be extended to probe for a specific class of chips.
