[PATCH] driver core: Remove unused platform_notify, platform_notify_remove

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>

The "platform_notify" and "platform_notify_remove" hooks have been unused
since 00ba9357d189 ("ARM: ixp4xx: Drop custom DMA coherency and bouncing").

Remove "platform_notify" and "platform_notify_remove".  No functional
change intended.
