Staging: add CSR wifi module

This consists of two modules, the driver, and a "helper" module that is
just a wrapper around common kernel functions.  The wrapper module will
be removed soon, but for now it's needed.

These files were based on the csr-linux-wifi-5.0.3-oss.tar.gz package
provided by CSR and Blue Giga, and is covered under the license
specified in the LICENSE.txt file (basically dual BSD and GPLv2).  The
files were flattened out of the deep directory mess they were originally
in, and a few EXPORT_SYMBOL_GPL() were added in order for everything to
link properly with the helper module setup.

+    NAME
+        CsrLogLevelTextSet
+
+    DESCRIPTION
+        Set the text logging level for a given origin and optionally sub origin
+        by name. If either string is NULL or zero length, it is interpreted as
+        all origins and/or all sub origins respectively. If originName is NULL
+        or zero length, subOriginName is ignored.
+
+        Passing NULL or zero length strings in both originName and subOriginName
+        is equivalent to calling CsrLogLevelTextSetAll, and overrides all
+        previous filter configurations for all origins and sub origins.
+
+        Passing NULL or a zero length string in subOriginName overrides all
+        previous filter configurations for all sub origins of the specified
+        origin.
+
+        Note: the supplied strings may be accessed after the function returns
+        and must remain valid and constant until CsrLogDeinit is called.
+
+        Note: when specifying an origin (originName is not NULL and not zero
+        length), this function can only be used for origins that use the
+        csr_log_text_2.h interface for registration and logging. Filtering for
+        origins that use the legacy csr_log_text.h interface must be be
+        configured using the legacy filter configuration functions that accept
+        a CsrLogTextTaskId as origin specifier. However, when not specifying an
+        origin this function also affects origins that have been registered with
+        the legacy csr_log_text.h interface. Furthermore, using this function
+        and the legacy filter configuration functions on the same origin is not
+        allowed.
+
+    PARAMETERS
+        originName - a string containing the name of the origin. Can be NULL or
+            zero length to set the log level for all origins. In this case, the
+            subOriginName parameter will be ignored.
+        subOriginName - a string containing the name of the sub origin. Can be
+            NULL or zero length to set the log level for all sub origins of the
+            specified origin.
+        warningLevelMask - The desired log level for the specified origin(s) and
+            sub origin(s).
