Subject: [PATCH v1 4/4] bus: mhi: core: Enable support for event ring priorities

Priority set in the event ring configuration by the controllers
has been unused by the MHI host driver until now. Enable usage of
those priorities set with the introduction of the enums for
default or high priority tasklet scheduling options.
