[PATCH v4 2/2] ARM: dts: AM33XX: update rtc node compatibility

[Hebbar, Gururaja]

From: Hebbar Gururaja <gururaja.hebbar at ti.com>

Since AM33xx RTC IP has RTC_IRQWAKEEN to support Alarm Wake-up, update
the rtc compatible property to enable handling of this feature inside
rtc-omap driver.

Changes in V4:
	- No change.

Changes in V3:
	- Instead of replacing the old matching string, add new
	  matching compatible as 1st and maintain old compatible string
	  for backwards compatibility 

Changes in V2:
	- Add new compatible to existing one so that when driver
	  supports enhanced features of hardware, they are available
	  to the user else the basic functionality still works
