Ezequiel Garcia a728b97742 ARM: mvebu: Fix coherency bus notifiers by using separate notifiers
Currently, the coherency fabric support registers two bus notifiers;
one for platform, one for pci bus types, with the same notifier block.
However, this is illegal and can cause serious issues: the notifier
block is also a link in the notifier list and cannot be inserted twice.

This commit fixes this by using different notifier blocks (with the same
notifier callback) to set the platform and pci bus types notifiers.

Fixes: b0063aad5d ("ARM: mvebu: use hardware I/O coherency also for PCI devices")
