[patch 2.6.19-git] RTC Kconfig sorted by type

From: David Brownell
Date: Wed Dec 06 2006 - 20:48:45 EST

This reorders the RTC driver menu into separate sections, splitting out
the SOC, I2C, and SPI support to help make the menu easier to navigate.
(We got some feedback a while ago that it was "a mess" and hard to make
sense of...)

Signed-off-by: David Brownell <dbrownell@xxxxxxxxxxxxxxxxxxxxx>

---
Assumes the rtc-omap patch has been merged, and no other RTC drivers
have been added to this Kconfig menu.
