clearfog: update kernel to 5.9.1
This was a funny one:
- On 5.9, the PCIe interface on Clearfog does not work at all due to
some PCIe range overlap with something else [1].
- The patch [2] which converted spi-orion.c to use `gpiod` instead of
that plain-old GPIO was apparently broken, *OR* perhaps it is not that
patch, but just a result of the general GPIO brokeness on mvebu that I
reported earlier [3]. Anyway, I'm simply reverting that.
- There were also some mcp23s08-related segfaults introduced in 5.9.
Also, there's a bunch of other patches, and as always, these are
available as a git tree [4], too.
