[PATCH] ARM: mvebu: armada-xp-openblocks-ax3-4: Disable internal RTC

[Gregory CLEMENT]

There is no crystal connected to the internal RTC on the Open Block
AX3. So let's disable it in order to prevent the kernel probing the
driver uselessly. Eventually this patches removes the following
warning message from the boot log:
"rtc-mv d0010300.rtc: internal RTC not ticking"

Hi,

I plan to add this patch to mvebu/fixes once the v4.1-rc1 will be
released. I don't expect much comments about it, but there is time
for them if needed until the next PR.

Thanks,

Gregory
