[PATCH] ARM: dts: am57xx-beagle-x15: Add wakeup irq for mcp79410

[Nishanth Menon]

With the support in the generic PM framework for wakeirq and capability
added to the rtc-ds1307 driver to support this, we can now define the
optional wakeup irq to allow the RTC to wakeup the system from low power
modes as part of suspend.

This patch depends on upcoming merge for RTC
https://git.kernel.org/cgit/linux/kernel/git/abelloni/linux.git/log/?h=rtc-next&ofs=50

merge to master of:
9901c41bd019 rtc: ds1307: Support optional wakeup interrupt source
496a7ede6cac rtc: ds1307: Sort the headers
e28475b15b65 rtc: ds1307: Switch to managed irq allocation
27a1dce6528a rtc: ds1307: Convert to threaded IRQ

Tested with the above commits from linux-next: http://pastebin.ubuntu.com/12265857/

Could probably go in round 2 of merges for 4.3?

Applying into omap-for-v4.3/fixes thanks.
