PCI: Turn pcibios_penalize_isa_irq() into a weak function
pcibios_penalize_isa_irq() is only implemented by x86 now, and legacy ISA
is not used by some architectures. Make pcibios_penalize_isa_irq() a
__weak function to simplify the code. This removes the need for new
platforms to add stub implementations of pcibios_penalize_isa_irq().
