mfd: Add placeholders for WM8350 client devices
In order to avoid merge problems further down the line add placeholders for several of the WM8350 client devices and register them, otherwise the patches adding the client devices will all try to update the same code. Also remove redundant checks for null regulator platform devices while we're at it.
