nrf5: Fix misuse of flash bank number 

Make driver_priv point directly into the corresponding chip bank structure
and add a pointer to it to get back to its chip when it's needed. This
removes the need to keep track of any bank number, either global or chip-
local.

In addition, it simplifies the cases where the chip structure was just used
to access the chip bank fields; now they are directly accessible.
