Koen Vandeputte 5f24933309 ar71xx: Move some targets to tiny
Recent changes on ar71xx (switch to 4.14, memory compaction, ...) cause
an increase in kernel size, making it too big for some devices.

Move these devices to the tiny target, where kernel symbols and
optimization for speed are disabled, reducing the kernel size.

Devices:
- EnGenius ENS202EXT
- OCEDO Koala

Compile-tested targets:

- ar71xx->generic->default
- ar71xx->smallFlash->Default
