drm/i915: Generalise common GPU engine reset request/unrequest code
GPU engine reset handshaking is something that is applicable to both full GPU
reset and engine reset, which is something that is part of the upcoming TDR
per-engine hang recovery patches. Break out the common engine reset
request/unrequest code (originally written by Mika Kuoppala) for reuse later
in the TDR enablement patch series.
v2: correct indentation and drop unused returned value (Mika)
v3: We have forcewake during reset so use *_FW reg access (Mika)
