GPIO library does copy the of_node from the parent device of
the GPIO chip, there is no need to repeat this in the individual
drivers. Remove these assignment all at once.

For the details one may look into the of_gpio_dev_init() implementation.

Hi Andy,

I love your patch! Perhaps something to improve:

[auto build test WARNING on thierry-reding-pwm/for-next]
[also build test WARNING on rockchip/for-next v5.16-rc4]
[cannot apply to linusw-gpio/for-next next-20211206]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
