exynos5800-peach-pi: suspend/resume (still) broken

I've tried suspend/resume on peach-pi using v4.0-rc4, next/master and
samsung/for-next, and it doesn't seem to work on any of them.

The first problem was the exynos DRM driver is faulting so I had to set CONFIG_\
DRM_EXYNOS=n for testing in mainline, this is fixed in -next.

Note that RTC wake from "suspend to idle" seems to work, which
suggests that the RTC wake alarms are working fine.  I tried with both
the s3c and the max77802 RTC drivers (e.g. rtcwake -d rtc0 -m freeze

However, trying suspend to RAM (rtcwake -d rtc0 -m mem -s4), it never
resumes, and adding "no_console_suspend" doesn't give anything useful.

Anyone else having better luck with suspend/resume on peach-pi?

I also tried on exynos5422-odroid-xu3, but that doesn't seem to have
any working RTC drivers. :(
