libata: PATA driver for Celleb

Browse source 
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.
