[GIT PULL] fsi changes for 5.5

[Joel Stanley]

Hi Greg,

Here's a set of changes I'd like merged for 5.5. They've been well
tested in the openbmc tree over the past month or so as we've done
hardware bring up using them. Aside from the three fixes I applied
today they have seen time in linux-next too.

This is the first time I've sent you a pull request, so please let me
know if you'd prefer it done differently.

The following changes since commit 755b0ef68f1802c786d0a53647145a5a7e46052a:
