Lots of code paths were split to T19x specific code paths and structs due to split repository. Now that repositories are merged, fold all of them back to main code paths and structs and remove the T19x specific Kconfig flag.

Devfreq is a common framework that allows using
|
|
variety of different governors and changing
|
|
between governors on the fly. By default, no
