[PATCH] PCI/x86-64: build with PCI=n

Fix (most of) x64-64 kernel build for CONFIG_PCI=n.  Fixes these 2 errors:

1. arch/x86_64/kernel/built-in.o(.text+0x8186): In function `quirk_intel_irqbalance':
: undefined reference to `raw_pci_ops'

Kconfig change:
2. arch/x86_64/kernel/pci-gart.c:194: error: `pci_bus_type' undeclared (first use in this function)

Still does not fix this one:
drivers/built-in.o(.text+0x3dcd8): In function `pnpacpi_allocated_resource':
: undefined reference to `pcibios_penalize_isa_irq'
