octeontx2-af: Enable PCI master
Bus mastering is enabled by firmware, but when this driver is unbinded bus mastering gets disabled by the PCI subsystem which results interrupts not working when driver is reloaded. Hence set bus mastering everytime in probe(). Also - Converted pci_set_dma_mask() and pci_set_consistent_dma_mask() to dma_set_mask_and_coherent(). - Cleared transaction pending bit which gets set during driver unbind due to clearing of bus mastering (ME bit).
