ide: make legacy IDE VLB modules check for the "probe" kernel params (v2)
Legacy IDE VLB host drivers didn't check for "probe" options when compiled as modules, which was obviously wrong as we don't want module to poke at random I/O ports by simply loading it. Fix it by adding "probe" module param to legacy IDE VLB host drivers. v2: * don't obsolete old "ide0=dtc2278/ht6560b/qd65xx/ali14xx/umc8672" IDE driver options yet (per Alan Cox's request) and enhance documentation Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
