The S5M8763 MFD has no device tree compatible, and since board file
support for it was removed, there's no way to use this MFD. After
removing the remaining code for it from the MFD driver, also remove
support for it in the s5m RTC driver, and all remaining references to
it.

Actually, looks like this should probably go in via MFD, so I need an
RTC Ack.

There were comments on 1/2 so I was expecting a v2.

Krzysztof commented there about the removal of an enum value that's
actually removed in 2/2 since it would break the RTC driver if it was
removed in 1/2. He realised that and corrected himself. No need for v2
AFAIK, unless something else is found.

The patch should definitely go via one tree (or by waiting for it to be
merged upstream, I guess) since the order has to be kept.

Best regards,
David

Yep. I also gave review tags for both of these.
