ide: add "ignore_cable" parameter (take 2)
Add "ignore_cable" parameter:
* "ide_core.ignore_cable=[interface_number]" boot option if IDE is built-in
(i.e. "ide_core.ignore_cable=1" to force ignoring cable for "ide1")
* "ignore_cable=[interface_number]" module parameter (for ide_core module)
if IDE is compiled as module
v2:
* Add ide_port_apply_params() helper
- use it in ide_device_add_all() and ide_scan_port().
* Make it possible to later disable ignoring cable detection by passing
"[interface_number]:0" to /sys/module/ide_core/parameters/ignore_cable
(however sysfs interface is not enabled yet since it needs some other
IDE changes to make it work reliable).
