arm: rk3308_linux_aarch32[_debug]_defconfig: enable zram support

Browse Source 
Zram allows Linux to make more efficient use of RAM, since
the system can then hold more pages of memory in the compressed
swap than if the same amount of RAM had been used as application
memory or disk cache. This is particularly effective on machines
that do not have much ram space.

Enable:
echo 16M > /sys/block/zram0/disksize
mkswap /dev/zram0
swapon /dev/zram0

More detial: Documentation/blockdev/zram.txt
