FS#11958 - iPod Classic thick 160GB CE-ATA hack

Here’s a working but terribly slow and invasive hack to get the thick 160GB iPod Classic drive working.
This involves multiple core changes:
- Get rid of all on-stack sector buffers
- Align the remaining sector buffers to cacheline boundaries
- Fork the ATA driver to support CE-ATA as well

I currently believe that the slowness is mainly coming from the low sleep() resolution in Rockbox, and maybe over-yielding.

This patch is currently rather awful and will probably need lots of work before it can be included. Be warned.
