mfd: rtc-twl4030 driver

This adds a driver for the RTC inside the TWL4030 multi-function device.
It's a fairly basic RTC, with a wake-capable alarm.

Note that many of the pre-release Overo boards now in circulation can't
effectively use this RTC, because of a wiring error that puts its TWL
chip into "secure" mode.  (As in "secure yourself against tampering".)
This isn't an issue on other OMAP3 boards now supported in mainline,
such as Beagle and Labrador.

If you say yes here you get support for the RTC on the
TWL4030 family chips, used mostly with OMAP3 platforms.
This driver can also be built as a module. If so, the module
will be called rtc-twl4030.
