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.
