Add LBA48 support to AHCI driver
* linux/dev/drivers/block/ahci.c (port): Extend `capacity' field type to
unsigned long long. Add `lba48' field. Make `identify' field unsigned.
(ahci_do_port_request): When `lba48' is true, use WIN_READDMA_EXT and
WIN_WRITEDMA_EXT commands.
(ahci_probe_port): Test lba48 flag, read capacity and set `lba48'
accordingly. Display size in GiB above 10GiB.
* linux/src/include/linux/hdreg.h (WIN_READDMA_EXT, WIN_WRITEDMA_EXT): New
macros
(hd_driveid): Add `command_set_2' and lba_capacity_2' fields.
