If you want to be a stickler about it, peach-pi actually has a
max98091.  That requires code changes to the i2c driver, though.
...and unfortunately listing two compatible strings for i2c devices is
broken.  :(

It would be awfully nice to keep diffs between exynos5420-peach-pit
and exynos5800-peach-pi clean.  They're 99% the same.  I know this has
already gotten messed up with DP/HDMI were added, but there's no need
to make it worse.

Could you add these nodes in the same place within the dts they were
added in exynos5420-peach-pit?
