ide: legacy PCI bus order probing fixes
IDE PCI host drivers should register themselves with IDE core only when IDE driver is built-in, otherwise (IDE driver is modular and thus IDE PCI host drivers are also modular) the code has no effect and just complicates the probing. Fix it by adding new config option CONFIG_IDEPCI_PCIBUS (defined only when needed and invisible to the user) and covering by #ifdef/#endif the code in question. It turned out that "ide=reverse" was silently accepted but did nothing in case when IDE driver was modular, this is fixed now. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
