Neither "depends on" nor "select" makes sense to me here.  The driver
apparently works without it, and simply having BLK_DEV_INITRD enabled
doesn't prevent improper (according to some people) use of the driver.
If updating microcode is inherently unsafe when a real disk is mounted,
the driver ought to detect this and refuse the operation (possibly with
an override option).
