FPGA Manager changes for 6.6-rc1

- Marco's change fixes kernel-doc warnings.
- Yangtao's change converts to use devm_platform_ioremap_resource().
- Peter's change uses HWMON defined Macros for HWMON interfaces support.
- Rob's change explicitly includes correct DT includes.
- Marco's change adds KUnit tests for FPGA core.
- Xiongfeng's change converts to use pci_find_vsec_capability().
- Ivan's change makes fpga_xxx_class a static const structure.

All patches have been reviewed on the mailing list, and have been in the
last linux-next releases (as part of our for-next branch).
