Bug Description
[Impact]
Hybrid setups with KBL/BXT + AMD need gen9 sna backend backported to fix bugs that prevent using the discrete GPU via DRI_PRIME=1 envvar.
[Test case]
Run 'DRI_PRIME=1 glxgears'
[Regression potential]
Minimal, as the commits mostly touch the new backend, apart from two commits that are fixes for other generations too.
[Other info]
