nor->dev is not exactly what we should use since it points to the SPI
NOR controller device in the !SPI_MEM case, and those controllers can
be attached several SPI NOR devs. Ideally we should use mtd->dev, but
that requires splitting the MTD initialization and registration steps
so mtd->dev can have a valid name before registration time.

Anyway, I guess this change is good enough for now, just mentioned the
problem in case anyone is interested working on it.
