sh: make gpio_get/set_value() O(1) This patch modifies the table based SuperH gpio implementation to make use of direct table lookups. With this change the functions gpio_get_value() and gpio_set_value() are O(1). Tested on Migo-R using bitbanging mmc. Performance is improved from 11 KBytes/s to 26 Kbytes/s.
