The DMI callbacks, used for quirks, currently access the PMC by getting
the address a global pmc_dev struct. Instead, have the callbacks set a
global quirk specific variable. In probe, after calling dmi_check_system(),
pass pmc_dev to a function that will handle each quirk if its variable
condition is met. This allows removing the global pmc_dev later.

This does not fix a bug.. it is preparation for further cleanups that
are not queued to 5.10 stable. So this should not be in 5.10 either.

I'll leave this for now, it will be helpful for later.

thanks,
