At least on BCM4387, the D11 cores are held in reset on cold startup and firmware expects to release reset itself. Just assert reset here and let firmware deassert it. Premature deassertion results in the firmware failing to initialize properly some of the time, with strange AXI bus errors. Also, BCM4387 has 3 cores, up from 2. The logic for handling that is in brcmf_chip_ai_resetcore(), but since we aren't using that any more, just handle it here.
