So doing:

static void pci_rcar_fixup(struct pci_dev *dev)
{
if (dev->bus->ops == &rcar_pci_ops) {
dev_info(&dev->dev, "applying new dma mask\n");
dev->dma_mask = DMA_BIT_MASK(31);
}
}

DECLARE_PCI_FIXUP_EARLY(PCI_ANY_ID, PCI_ANY_ID, pci_rcar_fixup);

Did not work for me :(

Seems like it should work, do you have CONFIG_PCI_QUIRKS turned on?

Yes, see the print happening, just still PCI OHCI dies horribly.
