drm/i915: Extend Haswell GT1 PSMI workaround to all
A few times in CI, we have detected a GPU hang on our Haswell GT2 systems with the characteristic IPEHR of 0x780c0000. When the PSMI w/a was first introducted, it was applied to all Haswell, but later on we found an erratum that supposedly restricted the issue to GT1 and so constrained it only be applied on GT1. That may have been a mistake...
