  ipmi: Add Loongson-2K BMC support (2025-09-16 10:15:54 -0500)

----------------------------------------------------------------
Bug fixes and enhancements for IPMI

This request fixes a number of small bugs, but has some more major
changes:

Loongson-2K BMC support is added.  This is an MFD device and is
dependent on the changes coming from that tree.  There is a
conflict in the MAINTAINERS file and the MFD tree changes must be
there before this is applied.

The way the driver handles BMCs that have become non-functional
has been completely redone.  A number of changes in the past have
attempted to handle various issues around this, but nothing has
been very good.  After working with some people on this, the
code has been reworked to disable the driver and fail all
pending operations if the BMC becomes non functional. It will
retry the BMC once a second to see if it's back up.
