PNP: Fix compile error in quirks.c

Fix the compile error:

drivers/pnp/quirks.c:393:2: error: implicit declaration of function 'pcibios_bus_to_resource'

that occurs when building with CONFIG_PCI unset. The quirk is only
relevent to Intel devices, so we could use "#if defined(CONFIG_X86) &&
defined(CONFIG_PCI)" instead, but testing CONFIG_X86 is not strictly
necessary.
