After Kernel 3.7, the Tegra device will only support booting with DT. The
legacy Tegra RTC platform driver will not work anymore. This patch convert
the driver to support DT.

I think Andrew Morton usually ends up picking up drivers/rtc/ patches
since Alessandro hasn't been active recently. But since Andrew wasn't
Cc'd, I'd be happy to take this through the Tegra tree for 3.9.
