I was referring to that of child, now in gpmc_nand_init(),
gpmc_cs_request() is being done, later on if we want to
make it generic and remove gpmc_nand_init(), additional
information that would be required from DT at least is the
memory size to be reserved in gpmc address space for
the connected peripheral (assuming gpmc_cs_request()
would be done by gpmc driver generically later)

What I had in mind was example for external bus in [1],
but I had not looked deep into this aspect yet.
