Fix performance when using multiple SLI rings

Currently the driver allocates all of its SLI command and response ring
entries to one primary ring. Other rings get little, or no, resources.

Allow more resources to be given to ring 1

PCI hrd_type should be obtained with pci_read_config_byte() macro

Driver keys off of this field to report the proper adapter type.
The pci subsystem explicitly clears the multiport bit in the copy of
the field given the driver. Thus, to properly name the card, obtain it
from config space.

Begin introducing the concept of sas remote devices that have an rphy

The next and more complex piece will be expander remote devices.

In order to use the new execute_in_process_context() API, you have to
provide it with the work storage, which I do in SCSI in scsi_device and
scsi_target, but which also means that we can no longer queue up the
target reaps, so instead I moved the target to a state model which
allows target_alloc to detect if we've received a dying target and wait
for it to be gone.  Hopefully, this should also solve the target
namespace race.

When the locking was changed in the eh code ips_eh_reset was changed
so that it was a wraper around __ips_eh_reset and all ips_eh_reset
does is grab the host lock and then calls __ips_eh_reset.

In the queuecommand, ips_queue is called with the host_lock held so if
it calls ips_eh_reset we will have a problem. This patch just has
ips_queue call __ips_eh_reset.

Patch is only compile tested. I do not have the HW.
