6ebf198203 fpga: fix potential null pointer deref in fpga_mgr_test_img_load_sgt()
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().

dbcbd3650f fpga: Simplify and improve fpga mgr test using deferred actions
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.

fpga: tests: use KUnit devices instead of platform devices
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.

fpga: add an initial KUnit suite for the FPGA Manager
The suite tests the basic behaviors of the FPGA Manager including
programming using a single contiguous buffer and a scatter gather table.
