4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Aaro Koskinen aaro.koskinen@iki.fi
commit dcf300a69ac307053dfb35c2e33972e754a98bce upstream.
Don't set octeon_dma_bar_type if PCI is disabled. This avoids creation of the MSI irqchip later on, and saves a bit of memory.
