fpga: fix potential null pointer deref in fpga_mgr_test_img_load_sgt()
fpga: m10bmc-sec: change contact for secure update driver
fpga_mgr_test_img_load_sgt() allocates memory for sgt using
kunit_kzalloc() however it does not check if the allocation failed.
It then passes sgt to sg_alloc_table(), which passes it to
__sg_alloc_table(). This function calls memset() on sgt in an attempt to
zero it out. If the allocation fails then sgt will be NULL and the
memset will trigger a NULL pointer dereference.
Fix this by checking the allocation with KUNIT_ASSERT_NOT_ERR_OR_NULL().

Use deferred actions to simplify the test suite and avoid potential memory
leaks when test cases fail. Remove unnecessary calls to
kunit_device_unregister() since kunit devices are tied to the test context
and released by a deferred action when the test is completed.
Other changes: fix a typo by changing the test suite name to fpga_region in
the kunit_suite struct.

This reverts commit a3fad2e92c.
The core components of the subsystem no longer assume that low-level
modules register a driver for the parent device and rely on its owner
pointer to take the module's refcount. KUnit test suites can now be safely
re-enabled with loadable module support.

KUnit now provides helper functions to create fake devices, so use them
instead of relying on platform devices.
Other changes: remove an unnecessary white space in the fpga region suite.

The fpga core currently assumes that all manager, bridge, and region
devices have a parent device associated with a driver that can be used
to take the module's refcount. This behavior causes the fpga test suites
to crash with a null-ptr-deref since parent fake devices do not have a
driver. This patch disables all fpga KUnit test suites when loadable
module support is enabled until the fpga core is fixed. Test suites
can still be run using the KUnit default UML kernel.
