transitioning from 4.17.18 to 5.0.6

[Patrick Venture]

HI, I ran into some weirdness when transitioning from 4.17.18 to 5.0.6
with the quanta-q71l board.  More specifically now my host can't talk
to the BMC via ipmi-bt.  All it returns is 0xd5.  on the BMC itself, I
can talk to ipmid file via dbus, and btbridge is running.

Has anyone else run into weirdness?

I am seeing:

[    4.645814] ipmi-bt-host 1e789140.ibt: Found bt bmc device
[    4.650341] ipmi-bt-host 1e789140.ibt: Using IRQ 32

The dts file I'm using is basically identical to the upstream one, and
my defconfig is also nearly identical to what's in meta-aspeed for the
ast2400.
