gpio: revert bank bindings

Browse Source 
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.

the fact that the hardware was synthesized by reusing the same IP block a

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
