[PATCH 2/6] New iswmd parameter for kernel cmdline

[Jacek Danecki <Jacek.Danecki@xxxxxxxxx>]

This patch add support for new iswmd parameter passed to the kernel command line.

When this parameter is added to the command line it will change support for isw_raid_member format:
- isw_raid_member is removed from udevTypes for DMRAIDMember
- isw_raid_member is added to udevTypes for MDRAIDMember
- md_uuid will be read from udev database
