Kernel/Storage: Add support for non-bus mastering IDE controllers

Browse source 
Although unlikely to happen, a user can have an IDE controller that
doesn't support bus master capability. If that's the case, we need to
check for this, and create an IDEChannel (not BMIDEChannel) to allow
IO operations with the controller.
