We should really start migrating away from this.

I would hope that the generic syscon would be enough for us. The issue 
would be to migrate all

syscon_get_first_range(ROCKCHIP_SYSCON_*);

we use in the code by checking the DT instead, e.g. rockchip,grf 
property for ROCKCHIP_SYSCON_GRF. For DT-less driver (e.g. SDRAM), I 
guess just using a hardcoded address would do just fine? Like, I don't 
understand what this brings us.

Anyway, a topic for another patch series :)
