ScsiLookup is an array of pending scmd pointers that the scsi lld
maintains. This array is touched from queuecommand, eh threads, and
interrupt context. This array should put under locks, hence this patch
to synchronize its access. I've added some nice little function
wrappers for this, and moved the ScsiLookup array over to MPT_ADAPTER
struct.

List below is output from C=2 sparse compilation, which are fixed with
this patch.
1) mptspi: pg0 is defined in x86 version of include/asm/pgtable.h
2) mptsas: context imbalance in 'mptsas_probe' different lock contexts
for basic block
3) mptbase: from mpt_attach - cast adds address space to expression
4) mptbase: from mpt_do_upload - request[] is bad constant expression

The Coverity checker spotted two potential memory leaks in
drivers/message/fusion/mptbase.c::mpt_attach().
There are two returns that may leak the storage allocated for 'ioc'
(sizeof(MPT_ADAPTER) bytes).
A simple fix would be to simply add two kfree() calls before the return
statements, but a better fix (that this patch implements) is to reorder the
code so that if we hit the first return condition we don't have to do the
allocation at all and then just add a kfree() call for the second case.

Per request from Matthew Wilcox - using PCI_VENDOR_ATTO.
Add support for ATTO UL4D, they are rebranded 53C1030.
The changes are
1. Adding a new PCI vendor ID in pci table
2. The spi_port_page_2 is in different format than that of LSI generic
spi_port_page_2 and hence mapping code is added.

If there is IO going to the volume while a hidden disk is being torn down,
there is a case where we would return a DID_NO_CONNECT for IO sent to the
volume. The end result is the volume goes read-only. This problem is due to the
fact the firmware mapped target ids saved in per device object is phys_disk_num
for hidden raid components, and target_id for the volume. There is a single
case when both phys_disk_num and target_id are equal, so enters this issue. We
fix this issue by checking the tflags when the device is torned down,
insuring the IO being completed is meant for hidden raid component, not the
volume. In addition to this fix, there are a couple other cases to address
hidden raid components. For instance task_abort and device reset are not
supported by mpt fw for hidden raid components, a bus reset would be required
or target reset to volume.

After host reset, the device are programmed to default asyn narrow nego.
We need to reprogram the parameter back to previous values. If the host
reset is called as a result of spi_dv_device() commands timing out, its
possible to get into an infinite loop of dv to host reset. This will
prevent that case, as we merely program old values. If host reset is
called outside context of domain validation, then we can call
spi_dv_device.
