arm: omap3: beagle: Ensure msecure is mux'd to be able to set the RTC

Without msecure beeing high it isn't possible to set (or start)
the RTC.

Tested with a BeagleBoard C4.

So if you're going to change the author, you'd also need to remove the SOBs.

It's likely just a glitch in patch generation.

Jindong: did you cherry-pick or git am this for the import
into your tree ? Or did you use another technique ?
If done properly, the author is always maintained in our
imported patches.

Cheers,

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]
