[yocto] [PATCH 1/1] RTC: Ensure msecure is mux'd to be able to set RTC

[Jingdong Lu]

From: Jingdong Lu <jingdong.lu at windriver.com>

commit e2a346a2a054f702fd76f328ff747b9ad9264a4c from git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap-2.6.git

arm: omap3: beagle: Ensure msecure is mux'd to be able to set the RTC.
"Msecure" signal provides for protection of the RTC register in TPS65950 be
disabling that function via a control signal from the OMAP3530. So ensure
msecure is mux'd to be able to set the RTC.

Tested with a BeagleBoard C4.
Fixes bug [YOCTO #767]
