Add MFD support for the DA9063 OnKey driver

The function da9063_clear_fault_log() is added to mitigate the case of a
hardware power-cut after a long-long OnKey press. Although there is no
software intervention in this case (by definition) such a shutdown would
cause persistent information within the DA9063 FAULT_LOG that would be
available during the next device restart.

Clearance of this persistent register must be completed after such a
hardware power-cut operation has happened so that the FAULT_LOG does not
continue with previous values. The clearance function has been added here
in the kernel driver because wiping the fault-log cannot be counted on
outside the Linux kernel.

I need this bit of pdata to merge the OnKey driver... Lee, any chance
you could drop it from the patch in your tree?

Consider it done.

Alternatively, can you pick the OnKey driver (the latest version is
below)?

Thanks.

Thank you both for your help.
