This updates the GPIO range documentation with the API changes
for sparse/random/arbitrary pin-to-GPIO mappings.

Why isn't this part of the pinctrl series you posted right afterwards?
(It should go in through that maintainer...)
For all functionalities dealing with pin biasing, pin muxing etc,
the pin
-controller subsystem will subtract the range's .base offset from the
passed
-in gpio number, and add the ranges's .pin_base offset to retrive a
pin number.
-After that, the subsystem passes it on to the pin control driver, so
the driver
+controller subsystem will look up the corresponding pin number from
the passed
+in gpio number, and use the ranges internals to retrive a pin
number. After
Range's perhaps?
