    i915/gem_workarounds: Verify regs directly

    It seems like the HW validator is getting better at preventing our
    snooping of system registers from non-privileged batches! If we can't
    use SRM, let's probe the register directly through mmio, making sure we
    have the context spinning on the GPU first.

    v2: Hold forcewake just in case the spinning batch isn't enough to
    justify our register access.
