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
