Add support for the FDMI-2 fabric switch feature.

Since FDMI-2 uses code from FDMI-1, some of the existing code
needed to be repaired to prevent fields from being overflowed.

During a chip reset, the mailbox call to get FC statistics from the ISP will
not work resulting in needless mailbox accesses and errors printing out:

To prevent this, check for a chip reset when an application queries for FC
stats and return immediately if a chip reset is occurring.

Add LLD target mode for >= 24xx series HW.  This code was originally based on
external qla2x00t module based on 8.02.01-k4, and has been refactored to
push the bulk of code into mainline qla2xxx.ko LLD -> qla_target.c.

The implementation uses internal workqueues for I/O context submission
into tcm_qla2xxx code, and includes the struct qla_tgt_func_tmpl API for
external interaction to allow qla2xxx LDD to function without direct
target-core dependencies:

It also enables qla_target.c usage within existing qla2xxx LLD code.
This includes:

*) Addition of target mode specific members to existing data
structures in qla_def.h and struct qla_hw_data->tgt_ops using
qla_target.h:struct qla_tgt_func_tmpl

*) Addition of struct qla_tgt_func_tmpl and direct calls into
qla_target.c logic w/ qlt_* prefixed functions.

*) Addition of qla_iocb.c:qla2x00_req_pkt() for ring processing, and
qla2x00_issue_marker() for handling request/response queue processing
for target mode operation

*) Addition of various qla_tgt_mode_enabled() logic checks in
qla24xx_nvram_config(), qla2x00_initialize_adapter(), qla2x00_rff_id(),
qla2x00_abort_isp(), qla24xx_modify_vp_config(), and
qla2x00_vp_abort_isp().

By default the new qlini_mode module parameter is setting initiator-mode
to 'enabled' in order for 'modprobe qla2xxx' to continue to function as
expected in initiator only mode.  Enabling target-mode operation will
currently require a:

    modprobe qla2xxx qlini_mode="disabled"

in order to explictly disabled initiator mode and allow target-mode
to be enabled via tcm_qla2xxx configfs fabric callers.

(nab: Convert to qlini_mode='enabled' by default in qla_target.c)
(joern: Remove loop_id from qla_tgt_make_local_sess() arguments +
        Remove unused s_id + fix s_id endianness bug +
        simplify qla_tgt_abort_work)
(gerard: fix section __exit mismatch in qla_tgt_exit)
(arun: Capture ATIO queue during firmware dump + Send SCR in target mode +
       Target mode review comments)
(roland: Don't create duplicate target sessions to address tearing down
         ACLs with IO in flight + Add missing call to qlt_fc_port_deleted
	 call during qla2x00_schedule_rport_del timeout)
