ARM_PCI_CFG_SIZE has the same value as PCI_CFG_SIZE. The pci driver uses
PCI_CFG_SIZE and arm uses ARM_PCI_CFG_SIZE when generating the pci DT node.
Having two defines with the same value is confusing, and can lead to bugs
if one define is changed and the other isn't. So replace all instances of
ARM_PCI_CFG_SIZE with PCI_CFG_SIZE.
