blackfin: gpio: Remove none gpio lib code.
- Remove non gpio lib code from blackfin architecture. - Limit the lagecy blackfin gpio driver to bf5xx processors only. - Remove unused definition of the pint power functions. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
