Subject: [PATCH v4 2/5] ARM: davinci: remove rtc kicker release

rtc-omap driver is now capable of handling kicker mechanism,
hence remove kicker handling at platform level, instead
provide proper device name so that driver can handle kicker
mechanism by itself

v2:
 Use device name da830-rtc instead of am1808-rtc
