I think it would be better to use "rockchip,rk3582" here, to allow
us to possibly use that information later.  For example, we might
want to be able to recognize RK3582-based boards in U-Boot without
the need to look into the e-fuses at some point, for which purpose
having a clear designator in the DT would fit perfectly.

As a reminder, using "rockchip,rk3582" would also require a small
addition to drivers/irqchip/irq-gic-v3-its.c.
