PCI: Move PHB lock to generic layer
All kinds of PHBs are maintaining a spinlock. At mean while, the
spinlock is acquired or released by backends for phb_ops->lock()
or phb_ops->unlock(). There're no difference of the logic on all
kinds of PHBs. So it's reasonable to maintain the lock in the
generic layer (struct phb).
This moves lock from specific PHB to generic one. The spinlock is
initialized when the generic PHB is registered in pci_register_phb().
Also, two inline functions phb_{lock, unlock}() are introduced to
acquire/release it. No logical changes introduced.
