[PATCH] PCI: CONFIG_PCI=n build fix

[PATCH] PCI: CONFIG_PCI=n build fix

With CONFIG_PCI=n:

arch/i386/kernel/cpu/cyrix.c: In function `init_cyrix':
arch/i386/kernel/cpu/cyrix.c:285: `cyrix_55x0' undeclared (first use in this function)
arch/i386/kernel/cpu/cyrix.c:285: (Each undeclared identifier is reported only once
arch/i386/kernel/cpu/cyrix.c:285: for each function it appears in.)

Make pci_dev_present() a macro.  It doesn't make sense to require that
pci_device_id's be in scope when CONFIG_PCI=n
