This patch set introduces initial KUnit test suites for the FPGA subsystem.

Tests can be run using:
[user@localhost linux]$ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/fpga/tests

v5:
- Removed most of the exported functions from fake components
- Moved all KUnit expectations/assertions to the main test module
- Removed standalone use case to simplify the code
- Removed instances counters from fake components (using device.id instead)
- Set header size in the .parse_header op
- improved bridge get_put_list test case

v4:
- Fix build error

v3:
- Calling fpga_bridges_put() between reconfigurations
- Functions for registering fake modules allocate and return context structs

v2:
- Restructured code into multiple suites to test components in isolation
- Reduced code duplication using init and exit methods
- Using a get_bridges() method to build the list of bridges just before programming
- Regions and Bridges are organized topologically
- Changed bitstream/bit to images
- Allocate images dynamically
- Renamed fpga-tests to fpga-test
- Simplified Kconfig
- Add license info to the fpga-test module

Marco Pagani (4):
  fpga: add fake FPGA manager
  fpga: add fake FPGA bridge
  fpga: add fake FPGA region
  fpga: add initial KUnit test suites
