The type checking is part of it, but it's more a general taste thing
with using swnodes like this.  You've not actually removed the board
file and it's hard to get enthusiastic about the change to the board
file that results, or to see this as a substantial step towards DT
conversion for the platform given the trivialness of the single
property here.  As a general thing I don't want to encourage people to
start randomly converting things to swnode rather than to DT.

The main difference with the GPIO lookup tables is that they are
structured data specifically for GPIOs rather than the general purpose
free for all we have with swnode.
