[PATCH v12 07/17] counter: Update counter.h comments to reflect sysfs internalization

[William Breathitt Gray]

The Counter subsystem architecture and driver implementations have
changed in order to handle Counter sysfs interactions in a more
consistent way. This patch updates the Generic Counter interface
header file comments to reflect the changes.
