drm/radeon/kms: add MSI module parameter
commit a18cee15ed4c8b6a35f96b7b26a46bac32e04bd9 upstream.
Allow the user to override whether MSIs are enabled
or not on supported ASICs. MSIs are disabled by default
on IGP chips as they tend not to work. However certain
IGP chips only seem to work with MSIs enabled.
I suspect this is a chipset or bios issue, but I'm not sure
what the proper fix is. This will at least make diagnosing
and working around the problem much easier.
