drivers/ide: PATA driver for Celleb

This is the patch (based on 2.6.19-rc4) for PATA controller of
Toshiba Cell reference set(Celleb). The reference set consists
of Cell, 512MB memory, Super Companion Chip(SCC) and some
peripherals such as HDD, GbE, etc. You can see brief explanation
and picture of Cell reference set at following URLs.

We use a drivers/ide driver because its design is more suitable for
SCC IDE controller than libata driver. Since SCC supports only 32bit
read/write, we must override many callbacks of ata_port_operations
by modifying generic helpers. Each time the libata common code is
updated, we must update those modified helpers. It is very hard for us.
But we will try to implement the libata driver as needed.
