I has downloaded TRM for this old Hi3519 SoC. So i think with the new
driver, it still works for Hi3519 FEMAC controller. So i'll rewrite
these 3 patches and describe the whole thing in commit logs. i.e. the
old binding is wrong, inconsistent with real hardware, etc..

So you mean conversion to YAML first, in a separate commit. And then do
necessary edition to match the real hardware? I believe Hi3519 FEMAC and
Hi3798MV200 FEMAC are compatible in hardware. So the old binding is
wrong, missing critical hardware resources.
