staging: most: move core files out of the staging area

This patch moves the core module to the /drivers/most directory
and makes all necessary changes in order to not break the build.

+	  This driver needs at least one additional component to enable the
+	  desired access from userspace (e.g. character devices) and one that
+	  matches the network controller's hardware interface (e.g. USB).
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called most_core.
+
+	  If in doubt, say N here.
