ff4e573db6 Add support for locate LED.
While here, change ISCI_LED to ISCI_PHY since conceptually the hardware
ties the LEDs to a phy and the LEDs for a given phy cannot be controlled
independently.

3715d30a3f Fix/add support for SCSI UNMAP to ATA DSM translation.
This addresses kernel panic observed when sending SCSI UNMAP
commands to SATA disks attached to isci(4).

1) Flesh out callback routines to allocate/free buffers needed for
   translating SCSI UNMAP data to ATA DSM data.
2) Add controller-level pool for storing buffers previously allocated
   for UNMAP translation, to lessen chance of no buffer available
   under memory pressure.
3) Ensure driver properly handles case where buffer pool is empty
   and contigmalloc returns NULL.

0cf3f85364 Add all isci driver source code to sys/dev/isci for the Intel C600
(Patsburg) integrated SAS controller.

sys/dev/isci contains all files specific to FreeBSD.
sys/dev/isci/scil contains OS-agnostic library maintained by Intel and
modified to best integrate into FreeBSD kernel build environment.
