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>

Everything else is rejected with a "BAD OPTION" message.
+For legacy IDE VLB host drivers (ali14xx/dtc2278/ht6560b/qd65xx/umc8672)
+you need to explicitly enable probing by using "probe" kernel parameter,
+i.e. to enable probing for ALI M14xx chipsets (ali14xx host driver) use:
+
+* "ali14xx.probe" boot option when ali14xx driver is built-in the kernel
+
+* "probe" module parameter when ali14xx driver is compiled as module
+ ("modprobe ali14xx probe")
