IPQ8064 MikroTik RB3011UiAS-RM DT have currently unevaluted properties
in the 2 switch nodes. The bindings #address-cells and #size-cells are
redundant and cause warning for 'Unevaluated properties are not
allowed'.

Drop these bindings to mute these warning as they should not be there
from the start.
