Redmi 4A (rolex) is like Redmi 5A with small differences like

fuel gauge, different speaker codec configuration and display.

I think an easier thing would be to just add a 'touchscreen' label
to the original one, /delete-node/ &touchscreen from rolex.dts and
add the new node there (seems like it's the only used) and do nothing
in the other two using EDT_FT5306
There is focaltech variant from rolex, and there is goodix variant from
riva and tiare,
maybe i should disable both node by default.
