Alex Elder 76be20a2f3 greybus: db3-platform: get rid of redundant gpio tests 
In apb_ctrl_get_devtree_data(), the value returned by
of_get_named_gpio() has a redundant test for a negative
return value.  GPIO numbers are non-negative, so this
test is redundant--testing gpio_is_valid() is sufficient.
