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. Acked-by: Rob Herring <robh+dt@kernel.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

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
