[Intel-gfx] [PATCH v3 5/8] drm/i915: protect HSW power well check with IS_HASWELL in redisable_vga

[Imre Deak]

From: Jesse Barnes <jbarnes at virtuousgeek.org>

This may need work if other platforms do the same thing, but in the
meantime we should avoid looking at HSW specific bits in this generic
function.

[added IS_BROADWELL too as that needs the same handling (Imre)]
