syscore: Changes for v6.19-rc1
Add a parameter to syscore operations to allow passing contextual data,
which in turn enables refactoring of drivers to make them independent of
global data. This initially only contains the API changes along with the
updates for existing drivers. Subsequent work will make use of this to
improve drivers.
