Public bug reported:
[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]
backported commits are:
15c5ff12459a034 sna: Clear damage tracking when marking as all-clear

c28e62f94f15c9f sna/gen2+: Do not force migration to GPU for very large objects
