ipod6g: Support MAX_PHYS_SECTOR_SIZE of 4K

Browse source 
This lets us *natively* handle varying physical sector sizes
without playing games and lying about the logical sector size.

(The original drives use 4K _physical_ sectors with 512B logical
 sectors, but you have to access everything in 4K blocks...)

Achieve this by splitting the MAX_PHYS_SECTOR_SIZE code out
of the main ATA driver and re-using it.
