[Intel-gfx] [PATCH 0/3] Enable HSW FBC

[Rodrigo Vivi]

Hi all, this small series enable Frame Buffer Compression at HSW.

I decided to create a new function haswell_enable_fbc to avoid getting old
function messed with many IS_HASWELL checks.

Also I decided to split the 2 needed workarounds in separated pathces to be
easy to revert at any time if needed.

On my local tests using a HSW ULT machine I could save around 0.1/0.2W.
Up to 0.3W. And apparently stable enough.

As always, reviews, comments, bikeshedings, tests, etc are welcome.

Thanks in advance,
Rodrigo.
