For following fc_host specific attributes, vports rely on the pport.
So, this patch changed way to access the data for those attributes so that
they can access pport's.
- get_host_speed (speed)
- get_host_port_state (port_state)
- get_host_port_type (port_type)
- get_fc_host_stats
Also, added PORT_SPEED_8GB case in the speed attribute for 8Gb HBAs.

Hmm, it looks like the conversion to resource_size_t usage

fixups to cleanup the structure-pointer castings used during IO mapped

There's only a small number of locations, where the driver uses IO
mapped accesses to the hardware, the patch below should take care of
it without introducing to many structural changes to code flow.

qla4xxx has the old school startup/probe where it finds presetup sessions
in its flash and then attempts to log into them before returning from the
probe. This however, makes it very simple to add a iscsi class scan finished
helper which the driver can use.
In future patches Dave or I will rip apart the driver to make it more
like qla2xxx, but for now this is a very simple two line patch which
fixes the problem of trying to figure out when the initial sessions
are done being scanned.

This just adds iscsi session scanning which works like fc rport scanning.

hardware iscsi root scanning.

Qla4xxx can just call the iscsi recovery functions directly.
There is no need for userspace to do this for qla4xxx, because
we do not use the mutex to iterate over devices anymore and iscsi_block
/unblock_session can be called from interrupt context or the dpc thread.
And having userspace do this just creates uneeded headaches for qla4xxx root
situations where the session may experience problems. For example
during the kernel shutdown the scsi layer wants to send sync caches, but at
this time userspace is not up (iscsid is not running), so we cannot
recover from the problem.
