What I don't understand yet about this new approach is where the gpmc
client code should live in. In order to probe the drivers via DT, each
driver would need to call the gpmc support functions itself, right? Is
the plan to obsolete helper functions like gpmc_nand_init() and move
that functionality to the drivers?

I applied these patches locally and would like to help get the NAND
controller on my AX33xx DT-driven board going. Let me know if I can do
anything here.
