FPGA Manager changes for 5.9-rc1

Here is the (slightly larger than usual) patch set for the 5.9-rc1 merge
window.

DFL:
- Xu's changes add support for AFU interrupt handling and puts them to
  use for error handling.
- Xu's other change also adds another device-id for the Intel FPGA PAC N3000.
- John's change converts from using get_user_pages() to
  pin_user_pages().
- Gustavo's patch cleans up some of the allocation by using
  struct_size().

Xilinx:
- Luca's changes clean up the xilinx-spi and xilinx-slave-serial drivers
  and updates the comments and dt-bindings to reflect the fact it also
  supports 7 series devices.

Core:
- Tom cleaned up the fpga-bridge / fpga-mgr core by removing some
  dead-stores.

All patches have been reviewed on the mailing list, and have been in the
last few linux-next releases (as part of my for-next branch) without issues.
