ahci: support LBA48 data reads for 2+TB drives
Enable full 48-bit LBA48 data reads by passing the upper word of the
LBA block pointer in bytes 9 and 10 of the FIS.
This allows uboot to load data from any arbitrary sector on a drive
with 2 or more TB of available data connected to an AHCI controller.

warnings on platforms that don't enable that feature ]
