libata: PATA driver for Celleb 



This is the patch for PATA controller of Celleb.

This driver uses the managed iomap (devres).

Because this driver needs special taskfile accesses, there is
a copy of ata_std_softreset(). ata_dev_try_classify() is exported
so that it can be used in this function.
