x86, acpi, pci: Move PCI config space accessors.

We are going to use mmio_config_{} name convention across all architectures.
Currently it belongs to asm/pci_x86.h header which should be included
only for x86 specific files. From now on, those accessors are in asm/pci.h
header which can be included in non-architecture code much easier.
