X86/PCI: Remove the dependency on isapnp_disable.

This looks to be vestigial dependency that had never been used even
in the original code base (2.6.18) from which this driver
was up-ported. Without this fix, with the CONFIG_ISAPNP, we get this
compile failure:

arch/x86/pci/xen.c: In function 'pci_xen_init':
arch/x86/pci/xen.c:138: error: 'isapnp_disable' undeclared (first use in this function)
arch/x86/pci/xen.c:138: error: (Each undeclared identifier is reported only once
arch/x86/pci/xen.c:138: error: for each function it appears in.)
