pci: pci_mvebu: Fix read_config() with PCI_SIZE_8 or PCI_SIZE_16
When reading 8 or 16 bits from config space, use appropriate readb() or readw() calls. This ensures that PCIe controller does not read more bits from endpoint card as asked by read_config() function. Technically there should not be an issue with reading data from config space which are not later used as there are no clear-by-read registers. But it is better to use correct read operation based on requested size.
