ocs_fc: IO timeout handling and error reporting fix.
Hardware timeout uses a 8-bit timeout value and expects the timeout to
be less than 255 seconds. Added software timer implemetation to timeout
and abort the IOs with timeout more than 255 seconds.
Fix the timeout problem by dividing CAM timeouts by 1000 as hardware
expects timeout value in seconds. Before this change, CAM timeouts in
milliseconds were getting truncated to 8 bits and converted to seconds.
So the actual timeout used when going down to the card would depend on
the bottom 8 bits of the timeout used.
Add the mapping of ocs_fc error status to CAM status.

Implemented Device Lost Timer, which is used to give target device the time to recover before marking dead.
Issue: IO fails immediately after doing port-toggle.
Fix: Added LDT(Device Lost Timer)- we wait a specific period of time prior to telling the OS about lost device.

Bring in the Broadcom/Emulex Fibre Channel driver, ocs_fc(4).
The ocs_fc(4) driver supports the following hardware:
Emulex 16/8G FC GEN 5 HBAS
LPe15004 FC Host Bus Adapters
LPe160XX FC Host Bus Adapters
Emulex 32/16G FC GEN 6 HBAS
LPe3100X FC Host Bus Adapters
LPe3200X FC Host Bus Adapters
The driver supports target and initiator mode, and also supports FC-Tape.
Note that the driver only currently works on little endian platforms. It
is only included in the module build for amd64 and i386, and in GENERIC
on amd64 only.
