NAK. SoC dtsi nodes are enabled by default, the actual "disable" in a
node only makes sense if that node has some dependency on board specific
physical dts property - such as pinmux etc that characterizes. This is
the discussion we have had and why selective muxes are enabled. CPU
cores make no sense to disable by default - you could have a case where
they may be efused out on a sub device variant, in which case, you are
perfectly valid to disable that node in the board dts OR if the sub
device variant is used on multiple boards, introduce a sub board variant
and disable it in the dtsi.
