Regression: Automatic selection of first device to read/write flash does not work anymore

[sylv-io]

As of the latest commit 436ac5c of #87, it is now necessary to specify the device for each read/write operation, even if only one device is attached. IMHO, in the case of a single device, it should be selected automatically.

$ ./dpcmd -d

By reading the chip ID, the chip applies to [  W25Q128BV W25Q128FV S25FL128K W25R128FV W25R128JV W25Q128JV ]
W25Q128BV chip size is 16777216 bytes.

@emmedve1 I think so. Try adding this flag: --device 1.
