And
Adds command header helper functions:
-ahci_command_header_set
-ahci_command_header_get,
-ahci_command_destroy, and
-ahci_cmd_pick
These helpers help to quickly manage the command header information in
the AHCI device.
ahci_command_header_set and get will store or retrieve an AHCI command
header,
