ata: pata_parport: Add missing protocol modules description

Most of the protocol modules for the pata_parport driver are missing a
module description, causing warnings such as:

WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/ata/pata_parport/aten.o

when compiling with W=1. Add the missing MODULE_DESCRIPTION()
definitions to avoid these warnings. While at it, also add the missing
MODULE_AUTHOR() definitions.
