disable ZRAM.

we don't need this. We have 2GB of RAM.
I used to run Windows Vista on 1.5GB of RAM. We have Linux and Android.
We also run on battery and general impression for zram is that's eating battery.
But if anyone wants to enable it, let's make it possible and keep it updated
with upstream.

You also need to make sure you make a startup script and put this in it,
for zram device init:
echo 1G > /sys/block/zram0; mkswap /dev/block/zram0; swapon /dev/block/zram0
