For the gpio_get_value()/gpio_set_value()/gpio_to_irq(), gpio_cansleep() functions, the custom version is only a micro-optimization to inline the function for constant GPIO numbers. However, in the coldfire defconfigs, I was unable to find a single instance where this micro-optimization was even used, and according to Geert the only user appears to be the QSPI chip that is disabled everywhere. The custom gpio_request_one() function is even less useful, as it is guarded by an #ifdef that is never true.
