Moved, renamed, and deleted files
The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure.

-/**
- * DOC: shared area - role and goal
- *
- * The shared area contains all the data exported by the upper layer to the
- * other layers. Since the bus and transport layer shouldn't dereference
- * iwl_priv, all the data needed by the upper layer and the transport / bus
- * layer must be here.
- * The shared area also holds pointer to all the other layers. This allows a
- * layer to call a function from another layer.
- *
- * NOTE: All the layers hold a pointer to the shared area which must be shrd.
- * A few macros assume that (_m)->shrd points to the shared area no matter
- * what _m is.
- *
- * gets notifications about enumeration, suspend, resume.
- * For the moment, the bus layer is not a linux kernel module as itself, and
- * the module_init function of the driver must call the bus specific
- * registration functions. These functions are listed at the end of this file.
- * For the moment, there is only one implementation of this interface: PCI-e.
- * This implementation is iwl-pci.c
