From: Balaji T K <balaj...@ti.com>
This patch adds support for RTC in phoenix TWL6030.
Register offset addresses which have changed in TWL6030 are defined under
CONFIG_TWL6030_CORE and CONFIG_TWL4030_CORE.
rtc-twl.c will hence forth support all twl RTC (4030, 5030, 6030 ..)

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.
+ will be called twl-rtc.
