Kernel/SysFS: Add /sys/devices/storage directory
This change in fact does the following: 1. Use support for symlinks between /sys/dev/block/ storage device identifier nodes and devices in /sys/devices/storage/{LUN}. 2. Add basic nodes in a /sys/devices/storage/{LUN} directory, to let userspace to know about the device and its details.
