drivers/block: Move PARIDE protocol modules to drivers/ata/pata_parport
Move PARIDE protocol modules out of drivers/block into drivers/ata/pata_parport and update the CONFIG_ symbol names to PATA_PARPORT. [Damien] The pata_parport driver file itsef is also moved together with the protocol modules in drivers/ata/pata_parport.

- aten.c is a low-level protocol driver for the ATEN EH-100
- parallel port adapter. The EH-100 supports 4-bit and 8-bit
- modes only. There is also an EH-132 which supports EPP mode
- transfers. The EH-132 is not yet supported.
