Simon Glass a219639d42 dm: Rename disk uclass to ahci
This started as 'ahci' and was renamed to 'disk' during code review. But it
seems that this is too generic. Now that we have a 'blk' uclass, we can use
that as the generic piece, and revert to ahci for this.

config BLK
bool "Support block devices"
depends on DM
help
Enable support for block devices, such as SCSI, MMC and USB
flash sticks. These provide a block-level interface which permits
reading, writing and (in some cases) erasing blocks. Block
devices often have a partition table which allows the device to
be partitioned into several areas, called 'partitions' in U-Boot.
A filesystem can be placed in each partition.
config AHCI
bool "Support SATA controllers with driver model"
depends on DM
help
This enables a uclass for disk controllers in U-Boot. Various driver
types can use this, such as AHCI/SATA. It does not provide any standard
operations at present. The block device interface has not been converted
to driver model.
config BLOCK_CACHE
bool "Use block device cache"
default n
help
This option enables a disk-block cache for all block devices.
This is most useful when accessing filesystems under U-Boot since
it will prevent repeated reads from directory structures and other
filesystem data structures.
