Can we pass in a wa_regs.txt (manual control) instead of using
i915_wa_regs (regression testing)?

I want to record the wa_regs from the end of the series and confirm that
the registers have the same values at the beginning of the series. We
can't check if regs have disappeared in between, but that way we can do
a quick check they haven't changed value.
