OMAP: add TI TWL92330/Menelaus Power Management chip driver 

Add Texas Instruments TWL92330/Menelaus Power Management chip driver.  This
includes voltage regulators, Dual slot memory card tranceivers and
real-time clock(RTC).

The support for RTC is integrated with this driver only; it is not separate
module.  Passes 'rtctest' on OMAP H4 EVM, other than lack of "periodic"
(1/N second) IRQs.  System wakeup alarms (from suspend-to-RAM) work too.

The battery keeps the RTC active over power off, so once you set clock
(rdate/ntpdate/etc, then "hwclock -w") then RTC_HCTOSYS at boot time will
behave as expected.

This driver can also be built as a module. If so, the module
will be called tsl2550.

If you say yes here you get support for the Texas Instruments
TWL92330/Menelaus Power Management chip. This include voltage
regulators, Dual slot memory card tranceivers, real-time clock
and other features that are often used in portable devices like
cell phones and PDAs.

If you say yes here you get support for the RTC on the
TWL92330 "Menelaus" power mangement chip, used with OMAP2
platforms. The support is integrated with the rest of
the Menelaus driver; it's not separate module.
