Add the '-@' DTC option for the Rock 5B and Indiedroid Nova devices.
These two devices are relatively new both with external GPIO headers
for expansion. This does impact the filesize of the DTB substantially.
rk3588-rock-5b.dtb 75352 -> 150094 bytes
rk3588s-indiedroid-nova.dtb 69507 -> 136739 bytes

I think that enabling this should be either left to Linux distributions,
to be enabled for all the dtbs they ship, which they already do, or be
enabled by us for all Rockchip DTs, instead of for enabling it just for
some boards. However, I think that leaving it to Linux distributions is
the preferred way.
