First of all there is no need to guard GPIO request by CONFIG_OF. It works for everybody independently on resource provider. While here, rename the function to reflect the above.
Moreover, since we have a global dependency to OF, the rest of conditional compilation is no-op, i.e. it's always be true.
Due to above drop useless #ifdef CONFIG_OF and therefore dead code.

You can ditch the .request_gpios callback and call fbtft_request_gpios() directly in fbtft_register_framebuffer(). That will make it safe to drop the OF dependency, otherwise .request_gpios will be NULL in the non-DT case. This is one of the bugs that follwed the gpio refactoring.
You can also ditch the .request_gpios_match callback if you want, it isn't called anymore (it is set in fb_agm1264k-fl).
