gpio: revert bank bindings 



Keep the words talking about what a GPIO bank is, but remove the
binding. We have not agreed that this is something we want to have.

A GPIO controller may specify a bank ID. This is a hardware index that

indicate the logical order of the GPIO controller in the hardware architecture,

usually in the sequence 0, 1, 2 .. n. The hardware index may be different

from the order of register ranges and related to the backplane of how this

one bank is connected to the outside through a pin controller for example.



Optionally, a GPIO controller may have a "ngpios" property. This property

indicates the number of in-use slots of available slots for GPIOs. The

typical example is something like this: the hardware register is 32 bits
