    drm/i915: hw readout support for ->has_pch_encoders

    Now we can ditch the checks in the Haswell disable code.

    v2: add support for Haswell

When I do S4 with kernel 88adfff1ad5019f65b9d0b4e1a4ac900fb065183, call trace
appears, the machine can't be accessed. I also tested it's parents, which
doesn't have this call trace. 
I attached jpeg of Call Trace of 88adfff1ad5019f65b9d0b4e1a4ac900fb065183 and
S4 information by serial port.
