gpiolib: fix gpio_do_set_config()
Commit d90f36851d65 ("gpiolib: have a single place of calling
set_config()") introduced a regression where we don't pass the right
variable as argument to the set_config() callback of gpio driver from
gpio_set_config(). After reverting two additional patches that came
on top of it - this addresses the issue by changing the type of the last
argument of gpio_do_set_config() to unsigned long and making sure the
packed config variable is actually used in gpio_set_config().
Fixes: d90f36851d65 ("gpiolib: have a single place of calling set_config()")
