gpio: Make of_count_named_gpios() use new of_count_phandle_with_args()
This patch replaces the horribly coded of_count_named_gpios() with a call to of_count_phandle_with_args() which is far more efficient. This also changes the return value of of_gpio_count() & of_gpio_named_count() from 'unsigned int' to 'int' so that it can return an error code. All the users of that function are fixed up to correctly handle a negative return value. v2: Split GPIO portion into a separate patch Tested-by: Andreas Larsson <andreas@gaisler.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Cc: Linus Walleij <linus.walleij@linaro.org> Cc: Rob Herring <rob.herring@calxeda.com>
