of/gpio: add default of_xlate function if device has a node pointer
Implement generic OF gpio hooks and thus make device-enabled GPIO chips
(i.e. the ones that have gpio_chip->dev specified) automatically attach
to the OpenFirmware subsystem. Which means that now we can handle I2C and
SPI GPIO chips almost* transparently.
* "Almost" because some chips still require platform data, and for these
chips OF-glue is still needed, though with this change the glue will
be much smaller.
