This series removes the fake platform_device used to initialize PM on
legacy davinci platforms, and also adds PM support for DT platforms.

Tested with legacy boot on da850-evm, and DT boot on da850-lcdk.  Used
RTC to wake from suspend-to-RAM: e.g. rtcwake -m mem -s 4 -d /dev/rtc0

With these patches applied, I saw the following randconfig build error.

arch/arm/mach-davinci/built-in.o: In function `davinci_pm_init':
pm_domain.c:(.init.text+0x13d8): undefined reference to `da8xx_get_mem_ctlr'
pm_domain.c:(.init.text+0x14bc): undefined reference to `da8xx_syscfg1_base'

Attached is the defconfig. I did not check to see if your patches 
introduced it or if this is something that always existed and never 
caught.

It looks like a new problem caused by moving those calls into pm.c.

The problem is that currently pm.o can be built even when da850 support
is not enabled, which is the case in your defconfig.

I'll hae a look at how to cleanup that dependency.
