Seems i2c2, i2c4 and i2c7 could be assigned to only one set of pins,
for them I'll add default pinctrls. For the other controllers, I prefer
to keep pinctrls in board-level devicetree, which is easier to read.
Other Rockchip SoCs (like rk3588) seem to provide default pinctrls even
for those capable of multiple groups of pins, so I'm not sure whether
it's necessary to keep the style synchronized. Will add if the
maintainer considers it's better.
